While going over the electricals/ connectors etc I pulled apart the power supply board for an overhaul and found it had been repaired a few too many times with lifting tracks, and was generally in a very bad state, so I designed and built my own power supply, making up my own PCB layout. I stuck with the original +60 volt and –12 volt regulator circuit designs, but came up with my own +5 volt regulator circuit based around an LM338K regulator IC.
