The latest on this project: I've now got a new belt kit (4 belts) and thus the next job is to dismantle more of the deck and then fit them. There's sticky grease on some of the brake linkages that needs cleaning out, for example.

Electronically it still seems to work, the cleaning of the pots and switches has cured the problems.

I've noticed what others have said about marginal power supplies. When testing the amplifier, the switch illumination bulbs do go dimmer when I turn the volume up into a loudspeaker load. But I probably won't be using normal speakers with it, as I mentioned I have a pair of Philips 22RH541s to use. Those have an input resistance of around 100 ohms, so shouldn't load the amplifier as much.
