38-7 dial switch stuck & possible bad field coil
07-03-2019, 08:01 AM
Both filter caps were replaced at some point, but the originals left in circuit. Wouldn't surprise me if they shorted. Unless I find a similar speaker, I'm guessing I'll have to replace it with a PM speaker and a 1.2k resistor (I'm thinking 25w would be enough). The original speaker had a humbucking coil - should I just increase the 2nd filter capacitor value to compensate for that? I think it was an 8mfd originally.
