[attachment=6620][attachment=6620][attachment=6620][attachment=6619][attachment=6619]I am restoring a Philco Jr Model 81. When I got this radio, I found a wire that was connected to the Oscillator Coil (fig 12 on the schematic) and the other end was taped off with tape. This is my first experience with a radio made in the 1930's and I can't determine where that wire should be connected. Along with the mystery wire (black), resistor #10 and Capacitor #5 in parallel are connected to the same lug as another black wire that goes to the Det Oscillator Tube #77. I have included a photo of the wire which I have put a green shrink sleeve for identification.
If someone has one of these radios on the bench, I would appreciate any help identifying where the mystery wire should be connected to. I have the radio recapped, resistors replaced that were out of toleranc and the radio does work, although the sound is somewhat distorted. It could be caused by this wire as is part of the oscillator circuit.
