Anyone seen this problem (including my friends at TT service, please

contacts ..... Surely someone has seen this ????
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.
