Robin: the initial silent amp problem seemed fixed when I unplugged one of the two speakers (suddenly there was sound, the other speaker worked fine). Once I unscrewed the non-working 1/4″ plug, then the non-working speaker worked too so it definitely seems like a shorted plug was the…[Read more]

I’ve tried the checks you suggested, to the limits of Google and my abilities anyway. Unfortunately, what I’m seeing doesn’t make a lot of sense to me:

– The negative feedback loop wiring is showing zero resistance from the 68K resistor to the speaker input jacks … that’s good.

– Neither of my…[Read more]

Just before pulling the board from the chassis to revisit the output transformer wiring, my son says: why don’t you try unplugging one speaker or switching where they’re plugged in?

Silly idea, won’t do anything, but it works …
