Now I need to find one of these, I had an opportunity to get one of t's non mystery control brothers, but I have a mystery control I should put to use. I have a few sets like this where someone was playing around under the chassis, typically things like adding phono jacks, external speaker connections, probably the worst one was a Rogers 10-12 I have where someone rewired the audio amp section from a class A-B power output, similar to a Philco 118, into just a class A push-pull setup.
