Cautions Before servicing the automatic changer, inspect the assem- bly to see that all gears, cams, springs, levers, etc., are cor

8、- rectly assembled and in good working order. 1. Never use force to start or stop the motor or any part of the record changing mechanism. 2. Warped or damaged records may cause the mechanism to jam. When jamming occurs, the safety clutch slips, causing a clicking sound. 3. A cracked or chipped recor

9、d may damage the sapphire. 4. Warped records may slide on one another while play- ing and result in unsatisfactory reproduction. .5. Do not leave the records on the record posts or on the turntable as they may warp, particularly in warm climates. Warped records may be flattened by placing them on a

10、flat surface with a heavy flat article placed on top of them for a few days. 6. If, for any reason, the mechanism stalls, turn off the turntable switch and remove the records from the posts. Start the turntable by turning the switch on and allow the pickup arm to complete its cycle. 7. Do not tighte

Check by applying power to the turntable motor, allowing turntable to reach full speed, then pull motor away

37、 from turntable drive disc. The turntable should coast for at least twelve revolutions. (In RP -162, dis- engage motor from turntable by pulling idler away from turntable to observe coast.) RP -160 Spring For use with Zinc Crystal: On RP -160 with aluminum pickup arm, and aluminum -cased crystal, th

38、e spring that governs pickup pressure is No. 30585: with zinc pickup arm and aluminum -cased crystal, the spring is No. 39673. When installing a zinc -cased cry- stal in a zinc arm, cut 11 turns off the spring, or install a No. 39754 spring. RP -160 Sapphire Pressure: The correct sapphire pressure i

39、n RP -160 is approximately 1 ounces. The pressure is governed by a spring inside the end of the pickup arm. Owing to the fact that both aluminum and zinc castings (with difference in weight) have been used for the arm and the crystal, and also that only the zinc crystal (Stock No. 39550) is supplied

40、 for replacement, In order to reduce idler wheel noise, the two metal washers have been replaced by two fiber washers in the Idler Wheel Assembly, Stock No. :36274, for the above record changers. The new fiber washers are Stock No. 39996, Tone Arm Stop Bracket: On 2nd production RP -158 and RP -160,

41、 a stop bracket has been added to the top of the motorboard to restrain the ton arm. It is mounted by means of the same screw, lock - washer, and nut used to mount the pickup shorting switch.

This has been corrected

48、by doubling the thickness of the end of the ratchet lever so that it presents a broader face to the edge of the drive cam pawl. The lever with double thick- ness is carried under the same Stock Number (38656) as the original lever, which it super- sedes.
