how to remove the cap on volume/power switch on Philco Mystery Set

[ipwizard]

Some of you might already know this.

I stumbled upon something today that I thought might be useful to others. If you ever find yourself overhauling one of Philco's Mystery Control sets (39-55, 39-116, 40-205 ect..) you will have a lot of rotten rubber wire to replace. Two of those rock hard wires lead to the power switch which is on a little platform and attached to a motor through a bunch of gears.

I originally thought that the switch would have to be taken apart to replace the wires for the power switch, but it turns out the cover is just a cap that can be pried off. This makes it super easy, and I missed this on my 39-116 which I’ll have to go back to and replace the wires I just slipped heat shrink over in the past.


Check out the pics.
