Terry,
I am dying to know the answer to the obvious question, after the second
"big-bang" how did you proceed. Did you reconfigure the parasitic
suppressors,
and if so, did this fix the problem? Did you decide to stop feeding the
amplifier new 3-500Z and just give-up? Or was there another fix?
Thanks,
Mike, W4EF............

Joe,
The amplifier WAS operating in it's normal configuration ... in fact it was
in standby ... no idling plate current indicated on the plate meter. When I
raised the lid nothing shorted !
Since this is what caused the "go-bump" as you put it I have to wonder what
other sort of little things could cause a similar occurrence. You tell me
what caused the 3-500Z's to come apart inside and short.
TNX,
Terry W6RU

It may well have been an oscillation but it might have been something
else that caused the tube to bias on in saturation. In any case, one
cannot call it a "parasitic" event since the amplifier was not operating
in its normal configuration.
Whether you "mistuned" the system or created a short somewhere by
lifting the lid is not really germane to the issue of tubes that "go
bump" while cut-off in standby.

So Joe, you think it was an oscillation? ... sounds like it to me also.
