Been a long time since I've restored one of these. Got the radio restored not the phono. Seem to remember the rubber parts had petrified over time.
The cut pair of wires in the first posting I'm thinking may have been for the phono lamp for illumination of the turntable. Operates from a limit switch on the front door.
The small transformer is for impedance matching the cartridge to the radio works. Cartridges are always bad after 60 years.
Correction: its a magnetic type, hence the impedance transformer.
Think the turntable motor is a shaded pole induction motor and normally works as long as it gets 110 VAC. I'm surprised it is running hot and not turning. Leads me to believe the motor winding has shorted turn.
Not sure which transformer mentioned is getting hot.
Recapping the radio will likely be needed sooner or later. Was not easy especially those electrolytic cans since the chassis underneath is cramped.
