I believe I have a model 432 Musiphonic from 1953 or 1954. It is to the right of the absoloutely georgeous Philco 48-464 on tha attached photo. I got them both in a package from Ebay. (The Philco was re-capped, cleaned and georgeous, I'm keeping that one.) Anyway, this little GE "mutt" is a 6 tube printed circuit dog's breakfast of a radio, but it does have a RF amp, 3 gang tuning capacitor, kind of interesting output transformer with a feedback winding, and the cabinet is perfect.
I recapped and cleaned the "mutt" (all the filter, bypass and wax caps) and I know I will have to replace the 35C5 socket, but there is an intermittent problem downstream that is shorting the B+. I tried blasting out the IF cans with Deoxit 5, and did a thorough decontamination of the pc board via mineral spirits brushed and wiped with paper towels, and left to dry for several days.
After that I was able to pull a couple of stations in, weakly, with garble and static, and current surges visable on the pilot lamp, and decided to stop before I burned the little sucker up.
The previous owner was, it seems, a rat who smoked. Now I am of a rat year (1948, and I smoke.) so that should not alone sentence this little box to death, or dismemberment to the crazy house of my spare parts.
I need a schematic, and would be very grateful if anyone has one and can make me a copy, or has tackled and won, or has tried and failed on one of these.
Thanks
