Philco Predicta On/Off Switch

[Electronic M]

Assuming you have a switch/pot on hand it should be easier than that... The power switch should be the same as in my debutante. It's mounted to a metal plate that is secured to the front with 2 nuts inside the cabinet and connected to the main chassis with ~1' of wiring harness.

You should be able to pull the volume and contrast knobs, remove the 2 nuts on the backing plate, pull the backing plate/switch/pot assembly out above the chassis then do the repair...

If you don't have a replacement or have an incompatible replacement you could solder a jumper across the switch terminals to make the set work till the right part gets sources.
