I thankyou Alek for that information. I don't think I'll pursue it
anymore. The amp I have is 15 plus years old with the original
3-500Z tubes and it still puts out 800 watts PLUS, with no sign of
arcing, at least not yet. I have never heard of corona washers
before belive it or not. I still learn something everyday, and that
is good.
