Sean Wrote: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.

Thanks for the info.
I will take a look at the caps.
Could I possibly retro-fit a rotary style tone control?
I have a junk philco chassis that has 2 of them.
Thanks
