I can't help on the tone switch. The tuning motor has a non-polarized electrolytic capacitor connected to it. If the capacitor is leaky (as it most likely is) the motor will not work. Also, there is a rubber "clutch" attached to the motor shaft that engages with a wheel to move the tuning capacitor. That rubber "clutch" is probably hard as a rock. When I restored one of these I bought a length of rubber rod from McMaster-Carr to make a new "clutch" from. I cut a piece to the proper length and chucked it up in the drill to sand one end to the proper profile for mating with the wheel.

Replaced the .01 non-polarized cap to no avail.
Still won't spin.
