If its one of those with a chunk of iron with the rotor in the middle held
by two bearings they were for getting much in the gap and then they ceased
up, Disassemble clean touch of lube in the bearings, reassemble adjust till
you can spin it and then try again.

I was trying to reconnect an ampolifier inside the case of a long unused
home-made record player. It was on its side and flipped over. Althought
everything looks intact, the motor will now not start. Power is getting as
far as a plug that fits into the motor.

I don't know whether to hang on to it or dump it. Who would want it not
working?

Have you tried giving the motor a spin with your fingers when it's
powered up?
