I would try and fix the power supply first. Probably just an open circuit resistor.

I actually wanna get rid of all the rest. I can just feed the audio into my own preamp circuit and I already isolated the button panel controlling the turntable. I just need to supply the turntable with the correct voltages through that 6 pin connector, but for testing purposes it would of course be very helpful to have the power supply running again.

There is this big board on the back of the machine that houses the power supply and the amp. I counted five fuses (is that what you mean by circuit resistor?) they all seem to be working. Are there more underneath or is there maybe a temperature switch inside the big transformer brick? It got really warm after my accident (I didn't check if it did that before though)
