I've never seen Ten Tec service answer anyone on this reflector, John.
Give them a phone call and they'll have some suggestions though.
I've had similar problems with my Hercules II, odd tripping of the amp,
inexplicable and intermittent. I talked to Ten Tec service and they
told me about some wiring going around a relay where some stray RF is
occasionally found :-) I "moved" the wiring around a bit and the
problem disappeared. I do not recall exactly the relay, I will go back
and consult my notes to see, but I recall a few wires going right next
to a relay on a board, I bent them and moved them into a very different
position. I also sprayed a tiny bit of DeOxit around on the connectors
while I was in there. It all worked fine after that.
