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' ?
