Trip not actuating clutch: 101?211-3' 101.211- When the trip rod (60) is turned, if the clutch pawl (63) does not move forward, engaging the 'pinion teeth, check for a loose pawl spring (49) or binding between the clutch pawl and the cam. if binding occurs, clean out foreign matter and check for freedom but do not oil. RECORD DOES NOT DROP WHEN CHANGER CYCLES: l. Spindle pusher shaft broken: If the pusher shaft ('74) is broken, the roller assembly ('18) will drop out of the spindle ('10). To replace the roller assembly, loosen the spindle screw (77) and remove' the spindle. Slip the pusher shaft return spring (85) over the pusher shaft and insert the roller assembly in the spindle. Turn the milled flat section at the top of the pusher shaft until it faces out of the milled o ening in the spindle. Press up on the roller until it raises about 1/8". Hook the pusher '71) around the pusher pin (72) and press the pusher back until it touches the spindle body. Push down and back on the pusher and slightly up on the bottom o! the roller assembly until the pusher snaps into place. 2. Pusher in spindle not moving far enough forward to eject a record: The pusher (71) should move up inside the spindle body. then move forward until it has reached a point flush with, or a maximum of .010" beyond the spindle body. To assuretha the pusher is all the way forward, the spindle roller should be raised hi h enough by the lift arm (4B) at the top of the cam face to slightly compress the roller spring(81?. See ' TURNTABLE STALLS DURING CYCLE" - '1. if the roller spring is compressed and the pusher does not move far enough forward to eject a record, the spindle should be replaced. If a recordis not pushed completely off the ledge, it may hang up on the spindle momentarily, then drop on the pickup arm when it moves in over the turntable. 3. Lift arm screw loose: Check screw (47) to determine if it is turned all the way in. 4. Pusher raises outside spindle body: When the changer cycles, the pusher ('71) should first rise up inside the spindle body, then move forward inside the center hole in the record. If the pusher rises outside the spindle body, it will raise the record instead of pushing it off the spindle ledge. Check the pusher I shaft ('14) to see if it is straight. If the shaft is bent, it will force the pusher forward 5. Lift arm roller broken off: If the lift arm roller (53) is broken off, the lift arm (48) will not turn when the cam (51) Two RECORDS DRoP_lg_r_oNcE_: 1. Hole in record too large: Check the diameter of the hole in the record. An oversize hole will cause two records to drop at once. 2. Spindle slide not fully down: If the spindle slide is not all the way down, more than one record may be dropped at a time. (a) Check the slide to be sure it is free and does not bind at any point. Clean out foreign- matter or straighten if necessary. Do not oil. I (b) When records are placed on the spindle, be sure the slide is all the way down. The slide will normally raise slightly as a record is being dropped but it should return to place immediately. 3. Record support binding on spindle or bent out of square with the shaft. The record support must be able to slide freely by gravity down the spindle. If the support does not follow the records down as they are being ejected, two or more records may be I binding occurs: (a) Check the spindle to determine if it is straight. Bend carefully with the fingers if b) Straighten the record support (3) if it is not square with the record support shaft. c) 'if the hole in the record support is not centered over the spindle after checking (a) and (b), bend the support shaft post on the base plate until the hole in the record support is centered over the spindle. (d) When the pin in the record support shaft has just entered the slot in the record support shaft post on the base plate, the play in the record support as it is swung from one side to the other should be equal on both sides oi the spindle. To correct bent position, hold the support shaft and carefully force the record support into the proper position. if the support is loose on the shaft, remove the knob and re-stake with hammer and punch. 4. Record pusher defective:  The record pusher ('11) may be deformed, etc. This may cause two records to drop at once. Replace the pusher. I (C)John F. Rider #### Page 6: RCD. CH.

Lift arm screw loose: Tighten lift arm screw (47). Pusher extending beyond outside diameter of spindle: Cycle changer by hand until roller assembly (78) is at the top of its travel. Using new record as a gauge pass it over spindle to see if it binds at any point. File off high points on pusher (71) with a fine file until record will pass freely over spindle. Pickup arm not adjusted properly: The adjustment procedure for the needle set down point is given under "ADJUSTMENTS" lf the hinge bearing (97) has been removed or the hinge bearing set screw (9) has been loosened, the relationship between the hinge bearing and the pickup arm locater assembly (98) must be reset. The procedure is as follows: Loosen the set screw (9) sufficiently to allow the hinge bearing to slide on the pickup arm locater assembly shaft. The set screw may be adjusted with an Allen wrench through the hole in the adjusting ring (11) located between the two adjusting screws (10) and (15). Place a 1/32" shim between the set down locater (101)and the ratchet arm (102). Turn the control knob to the "OFF" position. Place the pickup arm on the rest. In this position the arm extending from the set down locater should be engaged by the turned up leg On the control lever (44). Take up all the play between the parts by pressing up on the bottom of the ratchet arm and down on the top of the hinge bearing. 4Tighten the hinge body set screw (9) and remove the shim. _NEEDLE DOES NOT SET DOWN ON l()N RECORD IN PROPER POSITION! Pickup arm not adjusted properly. see "RECORD HITS PICKUP ARM"$ 4. Hinge catch does not return to 10" record position when changer cycles. (a) Stop the machine in mid cycle when the lift arm (48) has moved as far out as it will go and is about to move back to its starting position. Lift the pickup arm and see if there is a gap of at least 1/64" between the end of the leg on the catch (16) and outside step on the adjusting ring (11). The catch should be free to allow it to be pulled forward against the stop at the end of the leg on the adjusting ring. If/'there is not enough gap, check the setting of the hinge body and the pickup arm locater, see "RECORD HITS PICKUP ARM" - 4. If the setting is correct, the cam face on the lift arm (48) which contacts the round stud On the bottom Of the ratchet arm (26) may be bent. The ratchet arm should be forced around far enough to bring the pickup arm Out until the stop on the bottom of the hinge casting meets the stop in the base plate; then, to assure that the pickup arm is out as far as it will go, the lift arm should move the ratchet arm a few degrees further around, which will slightly compress the safety spring (93) and hold the pickup arm out firmly against the stop. Lubricate the hinge bearing with lubriplate. Do not use heavy grease. If the bearing between the hinge bearing and hinge body binds, the safety spring will compress instead of bringing the hinge body around firmly against the stop. Binding between safet spring and ratchet arm: If the safety spring ( 3) binds against the ratchet arm and does not hold the casting on the bottom of the pickup arm locater assembly (98) against the stop inside the ratchet arm, irregular needle set down will result. Disassemble the pickup arm locater assembly (98) by removing the lift arm (48), loosening the hinge bearing set screw (9) and pulling the ratchet arm and pickup arm locater assemblies down from the bottom of the changer. Hold the pickup arm locater shaft in one hand, turn the ratchet arm assembly to slightly compress the safety spring, release, and see if the safety spring returns the pickup locater casting firmly against the stop surface in the ratchet arm assembly. If binding occurs, remove the safety spring, see if the pickup arm locater casting turns freely in the ratchet arm casting. Remove burrs or sharp edge on end of safety spring, stretch safety' spring a little to increase tension and replace. Hinge catch does not disengage from the hinge cam: When the trip lever (7) has been depressed, it is held in the position until the catch (16) is disengaged, see "NEEDLE DOES No'r sET DOWN oN 12" RECORD IN PROPER POSITION" - 6. When the cycle is completed, if the catch does not disengage from the hinge cam (18): (a) Check to determine if the leg on the catch (16) is sliding down the incline on the leg on the adjusting ring (11), see "NEEDLE DOES NOT SET DOWN oN 12" RECORD IN PROPER POSITION' - '1. $The catch (16) and the hinge cam (18) are not disengaging when the catch leg is resting on the inside step on the adjusting ring. If this occurs, file the edge of the catch Which contacts the hinge cam until the two parts have a clearance between them of about 1/64" when the leg on the catch is on the inside step on the adjusting ring.

Diameter o! 12" record undersize: The set down position oi the needleI for 12", records is determined by the edge of the record striking the trip lever (7). , a 12 record has a diameter of less than the standard size o! 11 7/8 plus or minus 1/32 , it may fail to depress the trip lever far enough. Enlarged center hole in record: An enlarged center hole might effect as a small record. Pickup arm not adjusted properly: see ' RECORD nrrs PICKUP ARM" - 4. Binding between safety spring and ratchet arm: See NEEDLE DOES NOT SET DOWN ON 10" RECORD IN PROPER POSITION" - 3. Trip lever ,does not cock when 12" record drops: Allow a 12 record to drop to the turntable and shut off the changer just after it falls, before the pickup arm has a chance to move in over the record. The trip lever (7) should be forced down until the step on the hinge cam (18) passes the edge of the catch (16), preventing the hinge cam and the trip lever from returning to their original position. lf the trip lever does not stay down in a depressed position: (a) Check the catch (16) to see if it is free to move forward and engage the hinge cam. ) lf the stop on the hinge body (14) is defective, it might allow the pickup arm to move too far out, thus moving the trip lever away from the spindle. This will produce the same effect as an undersized record. Hinge catch does not go into inside step on adjusting ring when trlp lever is depressed: When the trip' lever (7) is tripped by a falling 12" record, the leg Aon the catch (16) should be moved out over the incline between the inside and outside steps on the adjusting ring leg and held in that position by the shoulder on the hinge cam (18) until the pickup arm starts to move in over the record. When this occurs, the leg on the catch should contact the incline and be moved out as it slides down the incline until the catch is disengaged and the trip lever can snap back up to a horizontal position. If the leg on the catch is not moved out far enough to enable it to slide down the inciine, file about the 1/64" chamfer on the edge of :he catch leg which contacts the incline. Check for binding between hinge surfaces or lack of lubrication may prevent fail to set the trip lever because it could produce the same body (14) and hinge bearing (97). Burrs on the bearing the hinge bearing from turning freely. Ratchet arm does not disengage from the set down locater when a cycle is completed. (a) There should be a 1/3 ' gap between the ratchet arm and the set down locater when the machine is not in cycle. If the gap is small enough to allow the parts t0 touch and bind as the needle moves across the record, the hinge bearing must be reset. See "RECORD Hi'rs PICKUP ARM" - 4. Hinge bearing binds. Place a block under the back end of the tone arm to prevent the needle from touching the turntable. With sensitive gram scale, check the amount of force required to move the pickup arm across the turntable. The force required should not exceed 2 grams. II the pressure required is excessive: I a) Check the ratchet arm and set down locater for binding. See 1, above. b) Check the bearing in the pickup arm post for binding. The bearing is located below the hinge bearing (97). To inspect it, loosen the set screw (9) in the hinge bearing. Uri-solder the pickup leads and pull them out through the hole in the hinge bearing. Pull up on the hinge and pickup assemblies. Clean foreign matter or corrosion from the bearings; Lubricate with light oil. To reset position, see "RECORD HITS PICKUP ARM - . Hole in record too large: lf hole in record is tOO large, the grooves may turn eccentric with the spindle and cause premature tripping. Binding in trip rod bearings: With the trip released, check the trip rod for play in the bearings. It should be free to turn without binding. Binding in trlii rod bearings.

Ratchet pawl not engaging the ratchet sector: lol 11 3' 1 ? u The ratchet pawl (2 ) must press against the ratchet sector forcing it back when the motion of theitpickup arm is reversed. If the pawl does not contact the ratchet sector or slides over : ' a) Check the pawl (29) for burrs around the hole. ) Be sure the pawl is free to turn on the bearing. If the drive pin (28) is driven down too far causing binding, the pin may be relieved by tapping up on the shank. (a) Check the pawl spring (27) for insufficient tension. d Check the point on the pawl. It should be sharp to enable it to dig into the ratchet teeth. Sharpen with stone if necessary. 4. Ratchet sector too far away from ratchet pawl: If the ratchet sector (34) is too far away from the pawl (29), the eccentric motion required to operate the trip will be excessive. Ii necessary, bend the trip bracket slightly to reduce this distance. If the sector is too close to the pawl, excessive trip pressure will result. 5. Needle jumps out of eccentric groove in record: (a) Check trip pressure, it should not exceed 8 grams for the trip shown in Fig. 2. If the pressure"is excessive, see "CHANGER TRIPS BEFORE NEEDLE REACHES END OF RECORD - 4 above. (b) The record may be defective. The trip groove is often too shallow. Check with a record which is known to be good. (c) The point on the needle may be bad. Check for a worn point. d) There may be binding inthe pickup bearing or ratchet arm. See 1 and 2, "NEEDLE DoEs NOT TRACK AcRoss RECORD PROPERLY". | 6. Clutch pawl binding on cam face: On the trip mechanism shown in Fig. 2 the clutch pawl (63) must be free to move forward and engage the pinion gear teeth when the trip rod releases it. Check for burrs or foreign matter lodged between the pawl and the cam. Do not oil as this might collect dirt and gum up the pawl.

Lift pickup arm and raise lift rod (94) by pulling xiii-g on the adjusting screw (13) as high as it will go. Feel the lift arm (48) for play. The rod may still touch the lift arm cam face, but it should not bind. I! binding occurs, the lift arm bearing may be bent or the fiber washer (59) under the lift arm should be removed to lower the liit arm. Spindle roller spring compressed too far. Cycle the changer and watch the relationship between the bottom of the roller spring housing ('78) and the roller (79). lust before the top of the lift arm cam raise is reached, the roller spring housing should stop its upward motion and the roller should continue up .005" to .047" more, slightly compressing the roller spring (81). If the spring compresses too much, the changer may stall on the shut off cycle. Check the lift arm bearin to determine if it is square with the base plate. It should be 90? to the base plate within 1 4?. If lt is bent, carefully pound into place with a soft mallet. If it is straight and the roller spring is being compressed too much, remove the fiber washer (59) betweei the lift arm and the steel washer under it.

NOISE DURING PLAYING 0F RECORD: l I (a) From motor: If a low pitched rumbling sound comes from the loud speaker while a record is being played, check the motor grommets (67) to be sure the motor is freely suspended on them. The motor lead wires should have slack to allow the motor to float. Motor rumble may also come from an out of balance motor rotor. In this case, the motor should be replaced. (b) From bearings: Defective turntable bearings can cause rumble. Check for foreign matter in the bearings defective balls, binding between balls and ball retainer. Rough surface iar?hvtvasiiiers. Clean ball bearing, sleeve bearing and washers, lubricate with lubriplate$ or

2. Defective motor idlerJheel: ,

A rapid thum ingi sound while the motor is running may indicate a flat spot on the motor

idler wheel (2 . Remove the turntable and check the rubber tire on the idler. If the surface

of the rubber tire is not smooth and even, replace the idler.
3. Defective needle:

A bad needle will cause loud needle scratch or hiss through both the speaker and the air

directly from the needle. For reduced needle scratch and 'needle talk" use a needle with I

high vertical compliance such as an offset "dog leg" type needle.

4. Defective record:

Worn or defective records cause needle scratch and distortion of the recorded sound. if the

record is warped, it may slip on the other records causing "wow", a waver in the recorded

sound. An enlarged hole in the record can also cause "wow".
5. Turntable scrapes:

If a scraping sound occurs as the turntable revolves check:

is) Turntable war d, causing outer rim to rise and tall.

) Motor idler (2 bent.
) Wires beneath turntable rubbing.

Squeaking sound as changer operates indicates lack of oil. Lubricate points indicated under

NOISE DURiNG cYchNG;

1. squeaks: see "LUBRICATION".
2. 'Grinding sound indicates lack of lubrication or worn parts:
Lubricate spindle roller assembly in bearing between it and spindle body.

_DISTORTION OF RECORDED SOUND:

1. Defective needle. see 3, "NOISE DURING PLAYING 0E RECORD'L.
2. Detective record. see 4, "NOISE DURmG PLAYDIG OF RECORD .
3. Defective pickup cartridge:
When the cartridge is defective, the recorded sound may be distorted, weak or stop entirely.
4. Defective amplifier:
Check phonograph, amplifier and speaker.

1. Binding inpickuparm. See l and 2, "NEEDLE DOES NOT TRACK ACROSS RECORD PROPERLY".

2. Defective needle. see 3, "NOISE DURING PLAYING OF RECORD".

3. Excessive needle pressure: ~
The pickup arm is designed to give the proper needle pressure when an aluminum cased cartridge
is used. If a cartridge with a die-cast housing is used, a compensating spring must he used
to bring the needle pressure down to the usual standard of 1 oz. to 1% oz. lf the needle
pressure is too great on a compensating spring, bend the long end of the spring.

CHANGER DOES NOT SHUT OFF AFTER LAST RECORD HAS BEEN PLAYED:

1. Record support bindin on spindle:
The record support (3 must rest on the offset shoulder of the spindle or the changer will not
shut off.
see 3, "TWO RECORDS DROP AT ONCE".

2. Changer stalls during shut off cycle.
See TURNTABLE SECTIONS: under "SERVICE INFORMATION.

3. Cutoff rod not engaging shoulder on spindle roller spring housing.
On the shut off cycle, the end of the cutoff rod (42) should contact the shoulder on the bottom
of the spindle roller spring housing (78) and turn the cutoff rod over 90?. If the end of the
cutoff rod passes under the roller spring housing as the machine cycles, on the shut off cycle,
a) The record support to be sure it is resting on the spindle shoulder, see 1 above.
b) The spindle to see if it is being held dawn in place by the spindle screw ('77).
c) The lift arm screw (47) to be sure it is tight.
d) The bent up end Of the cutoff rod (42) may be short. Replace if necessary.

PICKUP ARM DOES NOT SET DOWN ON REST AFTER LAST RECORD HAS BEEN PLAYED:

Control lever does not engage set down locater.

On the shut off cycle, one leg of the control lever (44) should catch the set down locater (43)
holding it to prevent the return spring (100) from pulling the pickup arm in. The pickup arm
should be held against the stop in the base plate. In this position, the nest in the pickup arm
should be directly above the pickup rest.

CHANGER SHUTS OFF PREMATURELY:

1. spindle roller spring compressed too far. see '1, "TURNTABLE sTALLs DURING cYcLE".
2. Roller spring in spindle too weak:
When the bottom record of a stack of ten 12" records is being ejected from the spindle ledge,
the roller spring (81) should not compress until just before the roller reaches the top of the
cam incline on the lift arm. If the roller spring is compressed under the load of a full stack
of records it may cause premature shut oif. Replace the roller assembly (78) if necessary.
3. Record too thick:
The changer is designed to play standard records. If an old style 1/8" thick record is used,
the changer will shut off instead of dropping the record.
4. Cutoff rod not being reset:

After the shut off cycle, when the cutoff rod (42) has been turned to throw the switch to the

"OFF" position, it should be returned to its original position the next time the machine cycles

bg' the bent up end of the cutoff rod, contacting the round stud On one leg Of the control lever

( 4). The flat s ring (46) acting against the cutoff rod should throw the rod against its stop

on the lift arm 48) and hold it there. If the cutoff rod is not fully) turned, the bent up end

next to the spindle may stick up high enough to prematurely contact the shoulder on the roller
spring housing ('78).

(a) Check the lever spring (46) for tension. Remove and bend slightly to increase tension if

b) Lubricate the cutoff rod bearings and around the lever spring with lubriplate or oil.

c) Check the clearance between the end of the cutoff rod (42) which passes under the control
lever (44) and the bottom of the round stud on the control lever. When the cutoff rod is
in its normal operating position, it should not clear the bottom of the round stud by more
than enough to completely turn the end of the cutoff rod from a vertical position back to
a horizontal position.
