Incidentally, assuming it was a belt drive device, there is probably a
little hole in the bottom of the motor to tweak the speed. a few made by
Mitsubishi seemed to actually have some servo based on pulses fed from the
turntable drive itself.


It is as you say going to be difficult without the circuit diagram to figure
out what the voltage range was.

Just been dismantling an old and very dead Ferguson music centre, probably
from the 70s. Nice little DC motor that powered the turntable, for which
I have another use in mind.

Using a bench power supply, the motor spins well at 5v, but I don't know
the voltage the motor was designed for, there being nothing stamped or
marked on it. Were these things fairly standard, and is 12v likely to be
the maximum voltage, or is that 'how long is a piece of string' ?
