Hello Tom:

I guess I didn't explain my situation very well.......When the problem
with the arcing/buzzing sound is coming from the amp, and the HV meter
is showing split second deflection at the same time as the arcing sound,
the amp is not in transmit mode, it does it even before the step start
timer kicks in, it continues to do it after the step start kicks
in.....I do not key it up because I am afraid to with it acting this
If the culprit is a 240 v line problem (socket faulty contact, or wiring
fault), just keying the amp (not transmitting, no RF at all) would let
the HV meter deflects very much lower than in normal condition. You may
verify this measuring voltage drop at 240V socket when keying at the
above stated condition.

way, so it is not RF getting back into the amp as some of you have
suggested......it cant be because there is no drive applied.
Thanks again.
