Also it is worth replacing Q anytime these sets come into the workshop with a BF Check R and D Replace R with a 47k 1 Watt version This value should be no less than ohms. As there is evidence of scorching on the board the use of a more substantial component would be indicated perhaps with small heatsink.

Check all large electrolytics in the secondary Ie bigger that uF , check all capacitors around IC error amp. Most capacitors you will find are leaking electrolyte. Might be a long job!!! A plastic cap fits on the spindle of the motor. This slips and doesnt grip the motor hence does not turn the drive gears. Just glue or replace the part use loctite or super glue.
