INSTALLATION

A.	UNPACKING

We advise that the packing case be carefully examined before unboxing the instrument, and should there be any indication of concealed damages, the transportation company should be notified. When unpacking we advise the following procedure:

1.	Remove the screws holding the back of the packing case to the sides.

2.	Carefully remove the instrument from the packing box.

3.	Open the doors in the back by means of the keys which are contained in cloth bag attached on the back.

4.	Remove the fastening from the tone arm to the tone arm post bracket.

5.	Remove the shipping block holding the rec-ord trays, and the shipping brace and wooden block which hold the motor rigidly for transportation purposes. It is advisable to keep these braces in the bottom of the instrument and use them again when transporting the machine.

6.	Remove the wood screws and blocks holding the brackets on the bottom of the record changer mechanism.

7.	Remove the four wing nuts in each corner of the chassis.

NOTE: The wing nuts should be removed so that the chassis may be resiliently suspended in the spring mounting. This is absolutely essential in order that the best tone quality may be obtained. When the instrument is again to be moved, these wing nuts should be replaced and tightened down so that they nold th.e chassis rigidly.

B.	CURRENT SUPPLY FOR INSTRUMENT

On the back of each instrument will be found a name plate which gives the type of current upon which the instrument is designed to operate. If in doubt as to whether or not the type of current at the location is correct, look at the house watt meter or call the local power company for this information.

C.	INSTRUCTIONS FOR INSTALLING RECORDS

A set of record support discs will be found fastened inside of the cabinet. One disc should be used as a support under-neath each record. It is not necessary to remove the record support discs from the trays when records are being changed, but it is important to make certain that both the discs and records are centered properly in the record trays.

When installing or replacing the records in the instrument, it is best to install or replace the record in highest numbered tray (#12, or #20) first.

Install or change the balance of the records starting with No. 1 tray and work down through the stack of record trays until all the records are in their respective trays. As each record is put in its tray the title for that particular record should be put in its proper place in the program holder.

After all trays have been filled they must be returned to their original position by hand excepting highest number (#12 or # 20) which should remain over the turntable.

D. NEEDLE

The Symphonola Pickup is designed to use any standard phonograph needle, however, we recommend the type supplied with the instrument. The needle should be installed having the flat part of the needle aligned parallel to the grooves in the record.

FUNCTIONS OF COMPONENTS IN SYSTEM

1. SYMPHONOLA

A. COIN SWITCH ASSEMBLY

When a 25¢ coin enters the runway of the coin switch assembly

(Fig. 29-B) it successively moves the levers of the coin switches Nos. 1, 2, 3, 4 and 5 downward, making a single contact for each lever moved. Each contact made should store a play in the play magazine.

Fig. 29-A is a front view of the coin switch assembly showingthe 5¢ and 10¢ runway. When a 5¢ coin enters, it travels down the right hand runway, moving the lever on No. 4 coin switch downward, making a single contact. This should store one play in the play magazine.

When a 10¢ coin enters, it travels down the left hand runway, moving No. 1 and No. 5 coin switch levers downward, making two contacts. This should store two plays in the play magazine.

B. METHOD OF SELECTING TRAYS IN THE SYMPHONOLA CHASSIS

When a selection is made one tray only should be pulled out at a time, The trays .are withdrawn by means of the selector slide pawls (Fig. 6H, No. 1183) of which there are twenty. One of

these slide pawls engages a lug on a tray (No. 1110) when one of the rollers (No. 1223) of the Helix (No. 3201) push against the selector slide pawl spring (No.1184) thereby moving the pawl (No. 1183) inward, as shown in Fig. 6B.

The selector pawls (Fig. 6H, No. 1183) are urged inward at all times by the action of the selector pawl springs (No. 1184).

But when the selector slide (No. 1180) is in position which the selector pawis opposite the lugs as shown in Fig. 6G, then the action of the selector pawl lift springs (No. 1113) is stronger and overcomes the pressure of the selector pawl springs (No. 1184) and prevents the selector pawls from engaging the lugs on the trays (Fig. 6G). That is, with the exception of that particular pawl which is pressed in through the action of the helix roller against the selector pawl spring (Fig. 6H, No. 1184).

C. MOTOR MOUNTING

The motor is resiliently mounted on steel springs (No. 1841 as shown in Fig. 5A) in order to prevent vibration from the motor being transmitted through the chassis and reaching the pickup.

D. RECORD PLAYING INDICATOR DIAL

The "record playing" indicator dial is located just back of the cabinet escutcheon and is illuminated by the same lamps that illuminate the program holder. It is timed with the selector in such a manner that is always indicates the number being played. On the hi-tone models 8800 and 9800 a single lamp illuminates both the record playing dial, the credit dial and the front vertical plastic.

E. RECORD PREFERENCE METER

A play meter indicating the number of plays obtained from each record is conveniently located and attached underneath the front shelf below the tone arm post. An individual dial for each record turns one notch clockwise as its corresponding record comes to playing position. A reading can be taken by first allowing the Symphonola to come to a stop after it has played No. 20-record, then lifting the cabinet lid and looking at the individual escutcheon dials under the. shelf. To reset the dials, turn them counterclockwise by hand until they reach the stop position. On models 8800 and 9800 it will be necessary to open the front door and turn on light by means of switch on right side of cabinet before playmeter can be read.

2. AMPLIFIERS

A.	GENERAL

The amplifier in the 1941 Symphonola is the source of power for all equipment located in the cabinet and also reproduces the sound recorded on a record. The power is supplied to various units by means of a plug and socket arrangement in which no plug can be put into the wrong socket. The distribution of power from the amplifier can best be taken up by describing the functions of each socket located on the front of the amplifier panel.

B.	FUNCTIONS OF SOCKETS AND SWITCHES

The power to all units in the Symphonola is controlled by the main switch (Fig. 11, Item 1; Fig. 14, Item 1; Fig, 17, Item 1). When this switch is in the down position, the Symphonola is inoperative. With the switch in the up position, standby power is supplied and the instrument is ready for operation.

The octal socket (Fig. 10,Item 3; Fig. 13, Item 3; Fig. 16, Item 3) supplies 25 volts to the solenoid drum from which point the 25 volts supply is distributed to the various relays and coils on the solenoid drum and electrical selector. This socket also has two lugs which are connected to the contacts of the motor control relay and they carry the power to the motor and amplifier when these contacts are closed. In addition, this socket provides the power to operate the counter unit located on the solenoid drum.

It will be noted that there is another octal socket (Fig. 10, Item 2; Fig. 13, Item 2; Fig. 16, Item 2) This socket supplies the power to a type T-3Z transmitter when one is used. From the schematic diagrams it will be seen that these two octal sockets (Fig. 9, Items M-21 and M-22; Fig. 12, Items M-21 and M-22; fig. 15, Items M-18 and M-19) are wired in parallel so that the solenoid drum and transmitter plugs can be interchanged without any harm resulting. The small 4 contact socket (Fig. 10, Item 1;Fig. 13, Item 1; Fig. 16, Item 1) receives the R.F. output from a type T-32 transmitter and carries the output to the A-C line.

The 9 contact socket (Fig. 10,	item 4; Fig. 13, Item 4; Fig. 16 Item 4) is the source of power for any remote control equipment that may be added to the Symphonola. The 2 contact outlet (Fig. 10, Item 5; Fig. 13, Item 5; Fig. 16, Item 5) supplies power to rnotor when the motor control relay contacts are closed.

The small 2 contact polarized socket (Fig. 10, Item 7; Fig. 13, Item 7) supplies 6 volts for the electrical selector and upper pilaster lights on the Model 8800 and 9800 Symphonolas. These lights are on when the main switch (Fig. 11, Item 1; Fig. 14, Item 1) is in the "on" position.

The 4 contact socket (Fig. 10, item Fig. 13, Item 6; Fig. 16, Item 16, item 6) supplies 117 volts to the primary of the lighting transformer (Fig. 1, Item 17; Fig. 2, Item 17; Fig. 3, Item 13). The power to this transformer is controlled by the light switch (Fig. 11, Item 2; Fig. 14, Item 2; Fig. 17, Item 2). When this switch is in the down position, all lights energized by the lighting transformer are on continuously. With the switch in the middle position, the above lights are off at all times. With the switch in the up position, these lights are on only when the motor control relay contacts are closed. The 4 contact socket (Fig. 16, Item 6) on Models 7800 and 7850 also supplies 117 volts to the program lights. These lights are on as long as the main switch {Fig. 17, Item 1) is in the "on" position.

The small 5 contact socket (Fig. 16, Item 7) on Model 7800 supplies 25 volts to the magazine magnet through the coin switches.

C. FUSES ON AMPLIFIER

There are two fuse receptacles (Fig. 10, Iterns 14 and 16; Fig. 13, Items 14 and 16; Fig. 16, Items 14 and 16) on the amplifier. The fuse (Fig. 10, Item 15; Fig. 13, Item 15; Fig. 16, Item 15) in the covered receptacle (Fig. 10, Item 14; Fig. 13, Item 14; Fig. 16, !em 14) is a 2-1/2 ampere cartridge type light fuse. The fuse (Fig. 10, Item 17; Fig. 13, Item 17; Fig. 16, Item 17) in the screw type socket (Fig. 10, Item 16; Fig. 13, It;em 16; Fig. 16, Item 16) is a 2-
1/2 ampere non-tamperable type fuse for tbe Symphonola motor. It is very important that a blown fuse be replaced with one of the correct value.

3. ELECTRICAL SELECTOR

A. GENERAL

The Electrical Selector supplements the mechanical selector; it is an electrical device located on the front of the Symphonola at which selections are made. Two models of the Electrical Selector differing in mechanical arrangement of parts are discussed in this manual. One is the type E selector which is almost identi-cal to the 1940 selector except the operating voltage is 25 volts. The other is the type C selector which has the same electrical characteristics as the type B out differs in that it consists of two comoonents the SA-62 Switch Assembly (Fig. 23) and the RB-6Z Relay Box (Fig. 24) --which are interconnected by means of a Selector Cable.

The Electrical Selector works in conjunction with the Solenoid Drum (Fig. 25) to control the rear helix of the Symphonola Chassis and effect the desired selection. The primary junctions of the mechanism in the electrical selector are (1) to establish credit in the selector mechanism, (2) convey selections to and establish them on the solenoid drum and (3) to cancel the credit established in the electrical selector when a selection is made. In addition, there are some secondary functions performed in the electrical selector which are necessary to prevent cheating and possible mistreatment or overloading of parts designed for momentary duty only.

The function of the components in the electrical selector will be discussed by considering the circuits involved. To simplify the following discussion, reference will be made almost entirely to the Type C selector. The explanations may be applied unchanged to analysis of the Type B selector operation.

B. COIN OR CREDIT CIRCUIT

The Coin Switch Assembly in the Symphonola operates in conjunction with the credit magnet (Fig . 24, Item 17; Fig. 19, Item M4) of the Electrical Selector to establish credit on the ratchet wheel (Fig. 24, Item 9). Each time a coln closes one of the contacts in the Coin Switch Assembly, the ratchet escapement lever ( Fig. 24, Item 13) is operated by the credit magnet and allows one tooth on the ratchet wheel to escape, rotating the ratchet wheel through an angle equivalent to one tooth.

C. SELECTOR SWITCH

The selector switches permit the operator to make the selection desired. It is so constructed that it is impossible to excite two selection solenoids at once. There are two fundamental circuits through the selector switches as shown on the Schematic diagram (Fig. 19) these are the red circuit and the black circuit as labeled. The red circuit is connected to the solenoid drum when a selector button is pressed. The black circuit permits the interlocking relay to function after the credit cancel solenoid has operated. The relationship of the switch segments is such that the black circuit is closed before the red circuit is completed. The red circuit is not closed but is left open when two or more selector buttons are pushed simultaneously.

A study of the Schematic Diagram (Fig. 19) will show how this happens. The purpose and the importance of this will be explained as other parts of the electrical selector are discussed.

D. SERIES RELAY CIRCUIT

When the credit switch contacts of the credit switch (Fig. 24, Item 24; Fig. 19, Item M3) are closed and the customer pushes a selector button, the series circuit is completed through the series relay to the corresponding selection solenoid on the solenoid drum. The credit circuit contacts are those nearest the front of the Credit Switch. When the series circuit is completed, the series relay contacts close and a selector pin is pushed up on the solenoid drum.

E. CANCEL SOLENOID CIRCUIT

The cancel solenoid circuit is completed through the cancel solenoid (Fig. 24, Item 2; Fig. 19, Item Ml) when the large contacts of the series relay close. The series relay thus energizes the cancel solenoid permitting a credit to be cancelled from the ratchet wheel.

F. INTERLOCKING CIRCUIT

When a selector button is pressed, the interlocking circuit (Fig. 19) is closed through one of the switch segments of the selector switch. After the cancel solenoid has traveled through the major portion of its stroke, it closes the contacts of the interlocking switch (Fig, 19, Item M6) operating the interlocking relay (Fig. 19, Item M17), which opens the series relay circuit and locks itself up by means of maintaining contacts.

G. INTERLOCKING RELAY

After the interlocking switch operates, operating the interlocking relay, the normally open or maintaining contacts close and maintain the circuit through the interlocking relay even though the interlocking switch contacts open.

When the normally closed contacts operate they break the circuit through the series relay (Fig. 19, Item M1). The series relay then drops out, the credit canceling solenoid ts de-energized; and the interlocking switch opens. As long as the selector button is held down, the interlocking relay will be energized and the starting relay and the cancel solenoid will be in their normal position ready for other selection to be made.

However, before another selection can be made, the interlocking relay must first return to its normal position allowing the series relay circuit to close.

This means that the operator cannot make another selection until he first removes his fingers from the selector button.

H. NON-CHEATING ClRCUIT

In order to prevent cheating by tapping the selector buttons lightly, a non-cheating circuit is included in the electrical selector. This circuit increases the period of time during which the series relay is energized.

The circuit is in series with the 30 ohm Cand ohm resistor (Fig. 19, Item M8). When the push button begins to travel backward, the interlocking circuit is broken some time after the series relay circuit is broken. If the series circuit is completed momentarily, energizing the series relay, the left hand contacts on the series relay will close and permit current to travel through the series relay by way of the non-cheating circuit until the interlocking circuit is broken at the selector switch. This current pulse is sufficient to operate the series relay long enough to cause a cancellation of credit. To further insure functioning of the non-cheating circuit when the push button selector switch is manipulated, contact gap A (Fig. 19) nas been included. It closes on the initial motion of the cancel solenoid plunger and connects series relay small contacts directly to the energy source.

I. ELECTRICAL COUNTER

To maintain proper operation of the electrical counter (Fig. 26, Item 7) on cancellation of the last credit, a circuit consisting of a resistor (Fig. 19, Item M9) and the contact set C (Fig. 19) is used. Its function is to prolong the energy pulse through counter relay (Fig. 26, Item 8) when Credit Switch contacts D (Fig. 19) break. The register is merely a means of limiting current through the circuit.

J. CREDIT INDICATING CIRCUIT

The credit on the ratchet wheel in the Electrical Selector is indicated to the customer by means of the credit indicating dial (Fig. 22, Item 34) . This dial is visible through the small window in the front escutcheon. The printed instructions on the front escutcheon explain this credit in terms of the number of selections the customer may make. The printing is not visible until credit is established and is illuminated with white light.

The type B selector includes a credit light switch which turns on the indicating lamps (Fig. 22, Item 53) .

4, SOLENOID DRUM ASSEMBLY

---------------------------

A. GENERAL

The Solenoid Drum Assembly(Fig. 25) works in conjunction with the Electrical Selector (Fig. 22 or Fig. 23 and 24) and the Symphonola Chassis (Fig. 40).

The Solenoid Drum assembly stores both selections and credit simultaneously. Means is also provided to cancel off selections as they are played from the Symphonola Chassis. The function of the component parts can best be taken up by a study of the individual functions performed.

B. SELECTIONS ON SOLENOIDS

When a selection is made in the Electrical Selector, a pulse of current travels to the Sole-Drum Assembly (Fig. 25) through one of the selector solenoids (Fig. 25, Item 11; Fig. 28, Item Ml) and pushes up the plunger and selector stop pin of that solenoid. The rotating selector disc (Fig. 25, Item 8) on the solenoid drum has a stop (Fig. 40, Item 7) which engages the selector stop pin (Fig. 25, Item 10) . The coupling shaft couples the rotating selector disc to the rear helix of the Symphonola Chassis and selects the corresponding record tray. After the proper record tray has been selected, the selection cancel switch (Fig. 25, Item 16) is closed and the selector stop pin is pushed dovm to its original position by means of the pin cancel relay (Fig. 25, Item 6),

C . CREDIT ON PINS

When a solenoid plunger is pushed up, credit is established on the solenoid drum. Contact is made between the plu_..ger contact spring (Fig. 25, Item 13) and the grooved metal contact on the lower nortion of the solenoid plunger assembly (Fig. 25, Item 12). This completes a circuit (Fig. 27) operating the motor control relay (Fig. 27, Item 12).

The motor control relay (Fig. 27, Item 12) contacts operate the Symphonola motor. These contacts close when a selector pin is up and do not open again until after the last selection has been played and the turntable has returned to its lowest position.

The solenoid plunger and selector pin are pushed down before the record has moved to the playing position, but the motor carry-over switch (Fig. 25, Item 17; Fig. 27, Item F-12) located on the rear of the Symphonola Chassis, keeps the motor control relay energized until the record has been played.

D. COUNTER UNIT

The Solenoid Drum type SD20-7Z is equipped with an electrically operated counter that operates every time a selection is made from either the electrical selector or from a remote control box. If one number is selected twice, the counter will register two selections. It operates every time a selecting pulse travels through any of the selector solenoids.

The counter unit is located inside the Solenoid Drum sub panel, and only the numerals are visible through the window in the side of the sub panel. To prevent tampering with the counter unit, the sub panel bottom plate is sealed with a small lead and wire seal, making it impossible to open the Solenoid Drum sub panel without breaking the seal.

Fig. No . 25 is a photograph of the Solenoid Drum SD20-7Z showing its assembly and miscellaneous parts and Fig. No. 27 is a Schematic Wiring diagram showing its electrical circuits.

OPERATION AND MAINTENANCE

1. GENERAL

A. APPEARANCE

It is important that the general upkeep and the good appearance of the instrument be maintained. A careful selection of good quality records appropriate for he location should be made. Typewritten or printed title slips should be used at all times. This not only adds to the attractiveness of the instrument, but increases its earnings.

B. LUBRICATION

Oil the gears occasionally using an automobile oil having a viscosity of SAE-10. Oil all friction points, such as the high speed transmission bearings and the selector feed clutch plates on the toothed rack. We recommend this oil inasmuch as ordinary light sewing machine oil on the turntable shaft, the transmission shaft, or the transmision bearings has not enough body to retain proper lubrication.

The slide grooves may be oiled sparingly should the record carriers become binding or sticky. If grease has been used in the slide grooves or the grooves become gritty or gummy, the record carrier may bind.

They should be washed thoroughly with a light grade of good quality lubricating oil. Wipe clean and re-oil sparingly. DO NOT USE VASELINE OB .ANY GREASE IN THE SLIDE GROOVES AS IT WILL GUM UP QUICKLY CAUSING A HEAVY LOAD ON THE SELECTOR SLIDE PLATE.

2 . TONE ARM

A. TONE ARM WEIGHT ADJUSTMENT

On Model 7800 the weight of the tone arm at the needle with the needle just barely clearing the record should be approximately 3.5 ounces.

On Models 7850, 8800 and 9800, Which use tone arm F-3110, the weight when tested as above should be 2.5 ounces.

When using the weight scale in Fig. 5, the indicator pointer of the scale should be directly opposite the needle screw just as the needle is leaving the grooves of the record.

If a weight test is made while the instrument is playing, it is easy to determine just when the needle starts lifting out of the grooves.

It is best to make all weight tests near the start of a record. On Model 7800 correct weight may be obtained by bending the flat spring underneath the tone arm upward or dovmward to decrease or increase the weight.

On Models 7850, 8800 and 9800 the correct weight may be obtained by turning the screw (located in the top and approximate center of the tone arm) in to decrease the weight, and out to increase the weight.

B . PICKUP

Two types of pickups (F-3121 and F-3126) are used interchangeably in the tone arm (Fig. When the pickup becomes defective, it is recommended that the entire unit be returned for a factory rebuilt pickup.

The pickup unit is a scientific device . Its characteristics are determined by its construction and the materials used. To dismantle the unit will reduce its magnetism, change the damping and introduce maladjustments which cannot be corrected. Such a unit will be of questionable quality and inferior to a factory rebuilt pickup which can be obtained on exchange for a nominal charge.

3. SOUND EQUIPMENT

A. AMPLIFIER

The amplifiers used in all of the 194l.model Symphonolas are designed to operate at any volume set by the control from very low to full output without distortion or bad tone quality. All the amplifiers are equipped with dual tone compensators; one compensator (Fig. 10, Item 19; Fi g. 13, Item 19; Fig. 16, Item 19) is used for modifying the high frequency or treble notes and the other (Fig. 10, Item 21; Fig. 13, Item 21; Fig. 16, Item 21) is used for modifying the lower frequencies or bass notes. Care should be used in adjusting these because by subduing either the high notes or the low notes to too great an extent, the tone quality and faithful reproduction of music will be greatly lmpaired.

B. VOLUME CONTROL

If the volume control (Fig. 11, Item 3; Fig. 14, Item 3; Fig. 17, Item 3) , which is located on the back of the amplifier panel, should cause the volume to jump to a high level when turned slightly and then go down again when turned slightly farther, the control is defective and should be replaced.

C . TUBES

When installing or replacing tubes, special attention must be paid to the designated number on each tube . The number on the tube must correspond to the number on the tube socket. Each tube must be inserted in its proper tube socket; failure to do so may result in damage to the tube. Make certain that each tube is firmly pushed into its socket to make proper contact.

D . SPEAKERS

The speakers (Fig . 1 , Item 4 ? Fig. 2, Item 4 ; Fig. 3 , Item 4 J used in each model Symphonola are designed and matched to operate with the other components which make up the sound equipment for that particular instrument and are built to withstand the full volume of the amplifier without injury. Care should be taken not to allow dirt to enter the speakers as this may cause a rattle or bad reproduction of music.

4 INSTRUCTIONS FOR INSTALLATION OF WIRED REMOTE SPEAKER

These instructions concern the remote speaker and the speaker volume control box for 1941 Symphonolas. A total of three speakers, including the speaker in the Symphonola, maybe connected to these Symphonolas.

The speaker control box is mounted on the inside of the extra speaker cabinet for packing purposes only. It should be removed and mounted on the bottom of the amplifier shelf with the control key 2-7/811 from the left hand wall (when viewing the Syrnphonola from the rear) on models 8800 and 9800. On Models 7800 and 7850, it should be mounted on the right hand wall (when viewing the Symphonola from the rear) with the control key 6-1/2" below the top of the mechanism mounting shelf. A plate which covers the hole for the control key must be removed for access to the control key of the speaker control box.

When connecting the speaker control box for use with the remote speaker, the following procedure is advised:

1.	Remove the green dummy plug (Fig. 10, Item 10; Fig. 13, Item 10; Fig, 16, Item 10) from the amplifier.

2.	Insert the plug from the speaker control box into either one of the two 7-prong speaker sockets (Fig. 10, Items ll and 12; Fig. 13, Items 11 and 12; Fig. 16, Items 11 and 12) .

3-.	Insert the plug from the remote speaker into either one of the 7-prong sockets in the control box.

4.	See the link on the speaker impedance matching panel (Fig. 10, Item 13; Fig. 13, Item 13; Fig. 16, Item 13) to correspond with the TOTAL number of speakers in use.

There are six positions on the key switch control in the speaker control box. When the control is in the full counter-clockwise position, the greatest amount of speaker energy reaches the Symphonola speaker. When the control is turned to the full clockwise position, the external remote speakers receive the greatest amount of energy. When the control is in the third position, turning in a clockwise position from the left, the energy reaching the Symphonola and external speakers is approximately the same.

The regular instrument volume control (Fig. 11, Item 3; Fig. 14, Item 3; Fig. 17, Item 3) is used to set the overall volume level desired.

armature is brought down it will push the selector stop pin into its normal position. If the reset shaft spring is too stiff, the armature may lack the necessary power to reset the selector stop pin. The strength of the spring may be reduced by removing a turn.

F.	SELECTOR DISC AND STOP PIN ADJUSTMENT

Under normal operating conditions, no adjustment of the Selector Disc (Fig. 25, Item 8) is necessary. However, if the Solenoid Drum is removed from the chassis and dismantled, some adjustments should be checked. If the plunger is pushed up slowly, the selector stop pin (Fig. 25,

Item 10) should mechanically engage the Selector Disc Stop before electrical contact is made between the solenoid plunger contact and the contact spring (Fig. 25, Item 13) .

G.	SELECTOR SHAFT ADJUSTMENT

There is an adjustment screw at the bottom of the solenoid drum assembly which regulates the end thrust of the selector shaft. There should be no side thrust of the shaft. The selector disc, which is on the shaft, should rotate freely. When this adjustment has been made, the locking nut on this adjustment screw should be tightened.

H.	COUNTER UNIT

Should the counter unit (Fig. 26, Item 7) fail to register each selecting pulse or fail to register at all, a check should be made to determine positively that the unit is actually defective.. If the unit proves defective, it should be returned for factory repairs and adjustment. The adjustment of unit in the field is not recommended.

I. COUNTER RELAY

The counter relay (Fig. 26, Item 8) controls the counter unit (Fig. 26, Item 7) . Each time the counter relay contacts are closed, the counter unit will register one more unit on the dials. Other than seeing that the contacts of the counter relay are kept clean (by using a contact burnisher when necessary) , no adjustments are recommended for this unit as the contact adjustments are rather critical. It is recommended that defective units be returned to the factory for adjustment or replacement.

SERVICE NOTES

I . PROPER NUMBER OF CREDITS FAIL TO REGISTER IN THE MECHANICAL SELECTOR

A MAGAZINE RELAY DOES NOT RESPOND TO COIN

If the magazine relay does not respond to a coin, a check should be made for a loose line cord connection at the wall outlet. The magazine relay magnet (Fig. 5A, No. F3207) may also be defective. There may be a broken wire or a bad connection on the magnet posts.

B. TOO FEW PLAYS FOR THE AMOUNT OF COINS INSERTED

The coin switches may not be making proper contact. If a coin switch fails to make proper contact it is usually because it has accumulated dirt or film on the contact surfaces or because the contact surfaces are pitted.

Dirt or film should be cleaned from the contacts and pitted contacts should be polished with a burnishing tool.

There may also be insufficient contact pressure. To correct this, the contact blades may be bent with

5. TURNTABLE DOES HOT FUNCTION PROPERLY

A.	TURNTABLE FAILS TO RISE TO PLAYING POSITION

If the turntable fails to rise to the playing position, there may be insufficient or faulty lubrication on the turntable spindle bearings. Use SAE-10 oil. DO NOT USE a light sewing machine oil.

Foreign obstacles such as dust or grit may enter the turntable bearings and cause the shaft to bind. Dirt and foreign matter may be removed from the turntable spindle as follows:

With the turntable in its upper-most position and the motor cut off, by means of the main switch, flood generously will oil, moving the turntable up and down with the fingers, and wipe off with a clean cloth . Repeat this operation until the shaft and bearings are clean. Re-oil lightly with No. SAE-10 oil.

If the turntable lift springs (Fig. SA, No. 1009) are too weak, replace with new springs from the factory.

It is possible that the turntable gears may be meshed too tightly. There should be slight play between the teeth of the turntable worm gear (fig. 4, No. l528A) and steel worm (Fig. 4, No. 1022) . he transmission

r

casing (Fig. 4, No. 1040) containing the steel worm assembly can	be moved away from the turn-

table worm gear (Fig. 4, No. l528A) to allow about .1)05" play between the teeth of the gears .

B.	TURNTABLE DOES NOT ROTATE WHEN IN PLAYING POSITION

The turntable clutch (Fig.'1, Wo. 1014) in the lower end of the turntable spindle should have a slight slippage to absorb the jar as it engages with the clutch pin underneath the turntable gear (No. 1528/,) . If the is clutch is too loose it will not drive the turntable. In this event, the clutch spring (No. 1315) should be replaced.

The turntable clutch (Fig.4, No. 1014) should engage the pin underneath the turntable gear (Fig. SA, No. 1528A) . With the turntable in the raised position, the turntable elevating

cam (No. 1006) should be clear of the cam roller (Fig. SA, No . 1016) so that; the turntable clutch will engage the clutch pin in the turntable gear. If the turntable elevating cam does not stop in the correct playing position, it n be slightly adjusted by means of the adjusting screw on the clutch release pawl (No. 1077) mounted on the turntable elevating cam (Fig. 1, No. 1006) .

A. CONTACT PRESSURE

The Motor Carry Over Switch (Fig. 8, No. 6179A) should be so adjusted that it will just open when 125 grams pressure (approx. 5 oz. ) is applied with a gram gauge on the movable blade at 1 inch from the end. This adjustment is made by means of a spring bender.

Sometimes the music will appear to be wavering or varying in loudness at a rather high rate causing a warbling of steady notes or a tremolo . Several things may contribute to this.

SWITCH ADJUSTMENT

ated until the turntable is .iust

at the bottom of its stroke. Under this condition, the switch is to be loosened and slid up or do1m until it just opens the contacts. It should then be thoroughly tightened at this point. After this is done, the Symphonola chassis should be operated and checked to see that the turntable stops just at the bot-tom of its downward stroke . This is a test of tn e timing adjustment. If it stops too late, the helix may be rotated over the r:ext p:Ln. If this happens and the next coin is selected it will be impossible for thls pin to be pushed all the way up because lt will be stopped by the Selector Disc Stop. If this particular number is selected , no play will result. On the other hand, if it stops too early, the turntable will not be completely at the bottom of its stroke and, as a result, it will be impossi-

ble to sl ide out the lower record

trays .

EFFECTS IN THE MU Sl C

Gummy oil or dry bearings will contribute to tone warble. The bearings should be washed clean and new oil applied .

The motor should be mounted free in its spring suspension and the couplings on the motor shaft should run true. If these couplers are eccentric or if the shaft is not properly aligned it might contribute to this warble effect.

.	MOTOR DOES NOT IS MADE ON THE

fl.	GENERAL

In all of the folloiVing discussions concerning the failure of the motor to start it is assumed that the selections were made and that the series relay in the electrical selector has operated. A cancellation of

credit is an indication that the series rel&y has operated.

B.	SOLENOID PLUNGER DOES NOT PUSH UP

If the solenoid plunger (Fig. 25, Item 12) does not push up, it is probably caused by a defective coil, or by dirt and grease gwruning the plunger and the	solenoid stop pin (Fig. 25, Item 10) . It is also possible that the selector stop pin may strike the stop on the rotating selector disc, which would prevent the solenoid plunger contact from being raised high enough to close the motor control relay, ee timig of motor carry over switch Section 9, paragraph 11C11.)

If the selector solenoid (Fig. 25, Item 11) is defective, it should be replaced as discussed under "Operation and Maintenance.''

\olhen the solenoid plunger and selector stop pin are sticking due to oil or dirt, the foreign matter should be cleaned from the moving parts so that they may slide freely . These parts should not be lubricaLed.

START WHEN A SELECT ION ELECTRICAL SELECTOR

C.	MOTOR CONTROL RELAY DOES NOT OPERATE PROPERLY

'llhen a solenoid plunger is pushed up, the grooved contact surface on the lower portion of the solenoid plunger makes contact with the plunger contact spring (Fig. 2!', Item 13) and operates the motor control relay. If the relay does not operate, it may be defective or 1t

may not be receiving energy. The

relay receives its energy from the 25 volt transformer on the

amplifier.

If the relay operates and the motor does IIOt run, the motor is probably defectlve or the con-tacts on the motor control relay

are not completlng the circuit,

also the n;otor fuse (Fig. 27,

Item 2) may be defective.

If the contacts are dirty,they may be cleaned with a burnishing tool. If they fail to make contact, the lower contact

blade may be bent with a contact

bending tool until there is wear allowance of at least 1/3211•

must work freely at all times.

If any adjustment is made here the unit should also

be tested with dimes since the wire feeler on this gauge also serves to deflect dimes into the proper path.

The rotary quarter sizer (Fig. 30, Item L) has no adjust-ment, but it is important that it work freely at all times, turning easily under the weight of a quarter. USE NO LUBRICANTS.

The scavenger wiper blade (Fig. 30, Item N) is effected by the adjustment of the deflector for fast m0ving 25¢ size slugs (Fig. 30, Item C) . It is im-portant that this part move freely and returns to its normal position when the scavenger is released, otherwise a quartermay be rejected.
