Thanks Jan. The motor runs quietly and the flywheel turns easily so at this stage I will assume the motor is ok.

I measured some of the AC voltages prior to the motor and am perplexed by them.

Instead of the specified 15V or 20V (Stop and Play modes), I am getting 27V~ and 38V~ across the motor run cap.

Across the dedicated 27V transformer winding, I am seeing 35V~ dropping to 33V~ in Play.

(The voltage carousel is set to 240VAC, btw!)

Is there some transformer failure mode that could give rise to these elevated voltages or could the servo be pushing DC back into the motor windings?

Can I disable the servo by temporarily removing TR2?

Thanks.
