An Introduction and a Philco 90 issue.
#43

I cut the electrolytics out of circuit (I should mention the BC resistor is still disconnected and out of the radio so the filter cap that's connected to BC resistor terminal 1 was already out of circuit) and I'm getting the same resistance measurements...3200 ohms when the speaker is plugged in and 90k ohms when the speaker is unplugged. I'm measuring this with my meter black lead clamped to the chassis and I'm measuring the terminal on the speaker socket that is normally connected to terminal 4 of the BC resistor with the meter red test lead. Just trying to be exhaustively clear so you can tell if I'm doing something dumb! Thanks so much for this help!

Absolutely no one is going to reverse engineer that circuit. Even the iron core is missing.RodB — 10:37 AM
