37-650 Parts Diagram & Schematic Don't Agree
#3

I'm just gonna tear it apart and wire it per the schematic. Don't ya just hate it when someone has chopped a set like this up. Hopefully that's all it is. We already know the schematic is wrong on the polarity of that 10ufd filter. Positive should go to chassis ground not negative as the schema shows.

EDIT: I revamped the audio circuit to match the schematic and it worked but the volume was low and it would motorboat if I turned it up. Disconnected the after market tone control from the circuit and the set works great. I need a tone control!!!

Thanks Morzh. So it appears I did wire it incorrectly and I have to switch the wires between pins 2 and 4.bobclausen — 09:24 AM

No, it's not a problem, just during certain condition it could show up. Yes, an internal tube short could do that too. ...morzh — 09:13 AM
