You know,
My self and a friend were battling just such a flash over problem in a 6M amp
that turned out to be the radio
putting out a pulse of RF sometimes when it was keyed.
Just out of curiosity, does this problem occur if you just run the tube from
cutoff to operational bias without the
exciter being active?
Just a thought....
