Reassembled, and powered up..no fire...no smoke..no buzz...no tubes glowing..no nothing....

Totally dead.

Did a bit of tracing of the power circuit through the on/off switch..and wouldn't it be a bummer if the set has been dead since around 1960 due to a bad power switch?

Well..the power switch IS bad. I jumped it and everything lit up on the bench. Still no explosions, no fire, no smoke, etc. But every tube lit up as it should.

Anyone have any luck repairing a power switch? If not, any idea where to get replacements? The switch is a combination on/off switch-volume control and hold control. I can solder in a temporary toggle switch for testing purposes.

I've posted a "Want Ad" with part numbers in the "Classifieds" section.

First, you have to determine what make of control it is. CTS, seems to be the most common. It could be Mallory, Clarostat, IRC or another East coast manufacturer.
Then, take the control all apart and transplant a known good switch.
One of the posters on this forum, could make up a control. IIRC, you sent them the defective control and they would repair or duplicate it.
