Ahh. So you think the source resistor is opening, taking away that reduced potential
needed to prevent heater cathode breakdown.... And once that happens you
think that is not effecting the cathode voltage ??? in a downward direction from
whatever short develops Heater to Cathode.... Interesting....
Oh-Ya My fingers are crossed.... Poor guy a couple-a years chasing this problem....
I wonder how many times this cropped up in the field.... and how long it took
other people to find it....
