    Hello, I am trying to repair an Audio Reflex record player of the DD-1979 make. The issue is thus: the turntable will not spin at all when the tone arm is placed on the record (there is no power switch, just the tone arm is supposed to activate the motor). I have tried oiling the motor, but it has made absolutely no difference; the motor is still completely dead. I know that the power supply is okay because the light goes on, and I visually checked both fuses to find that the filaments within were still intact. The capacitors did not seem to be bulging or leaking in any way. It is important to note that if the 33/45 switch is pressed while the power is on, the turntable does spin about an inch or two.

    Thank you. I am an amateur, so I am not sure if this will help me, but I will give it a go.

    I'm an amateur too. There are some voltages on the schematic which could help if you use a multimeter to check them.

    I do have a multimeter; the fact that the platter turned when I pressed the 33/45 switch is indicative that the motor is still getting power.

    That's true. I think you could work back from the motor checking voltages looking for any that are obviously wrong, but it's quite a complicated circuit. You could start swapping in new components if you can't think of anything better.

    Do you know how to test diodes and transistors with a multimeter ?

    Yes, but I don't have spare components on hand right now. I can't just swap them out, so I'll just have to check them.
