AC-201 OR AC-205 TURNTABLE MOTOR REPLACEMENT

REMOVING THE AMPLIFIER FROM THE CASE

Remove the cover from the unit, lift out the turntable platter and set it aside. Turn the unit upside down onto a pillow, foam or other material, be sure it is thick enough to support the amplifier and protect the tone arm. Remove the four screws, one near each spring foot. AT THIS POINT THE CHASSIS IS FREE FROM THE CASE AND EXTREME CARE SHOULD BE USED TO PREVENT DROPPING EITHER THE CASE OR CHASSIS. Holding the chassis and the case together, carefully turn the entire unit over to its upright position. The chassis can now be lifted out of its case, lifting the front first so as to clear the jacks on the rear panel.

INSPECTION AND FAMILIARIZATION

Turn the chassis upside down on the padding with the controls toward you. 

Note which wires go where and then unsolder the three leads, the two going to the motor and the one brown ground lead. 

Locate the tension spring which provides the spring tension to hold the motor assembly up so that the drive wheel contacts the underside of the platter. Remove the two nuts and washer from this bolt, remove the spring and the motor assembly will swing out so that you can get at it. Remove one of the hex bolts holding the motor mount to the bracket, slide the rubber grommet off the other bolt and the motor assembly will come out.

Install the replacement motor by following above instructions in reverse order.

After reassembly you might have to readjust the spring tension and this can be done without disassembling the system. Lift off the platter and locate the slotted adjustment screw, about 1/4 inch from the rim of the drive wheel. Loosen the locknut, and turn the screw clockwise to decrease the spring tension, or counterclockwise to increase tension. Tighten the spring no more than necessary. When the tension is correct, tighten the locknut and replace the platter and the turntable is ready for use.
