Does anyone know the voltages on the 3 secondaries
Main deck motor 12V but about 10.5V dc from the supply, nothing wrong

the ps and nothing wrong with the motor and its regulator. All that is

is the mains transformer.


Personally I'd suspect the motor first. Have you checked the current
draw by the motor? Sometimes as they age they draw more current.

Q: is the trasnformer running hot? If it is that would indicate a
problem (Shorted turns).


I happened to have a near exact salvaged motor to swap over , pinion is grub
screw fixed, so easy. Maybe both hare wrong the same way. Much the same
result of DC 12V and too slow deck drive. It maybe that the drivebelt is
super critical but the dc over the motor is only about 12V with another
belt, so loose, that the pinion slips under it.
Transformer seems fine, no buzz or heat.
