My Dad's Pioneer PL-A45D, full-auto belt-drive TT that has developed extreme motor vibration. The tonearm will literally dance across the record. At first it was an intermittent issue that has now become permanent.
At first, I assume it was a mechanical failure of the motor but he says the motor spindle and platter spin smooth by hand.
Could this be an electrical issue? Not much to the circuit (schematic is attached). PM is the drive motor and WM is the cueing motor.
If I had it in my hands I wouldn't bother you guys with this question, but it's at his place. Would failure of one of the caps cause this or should I write this off as mechanical failure and find him a new table?
