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.
