€  The 425 I worked on exhibited - with a Funderberg high-pot
gold-sputtering test, migrant gold damage in both 3cx800A7s........

I've seen the effect of leakage changing when anode/grid polarity is
reversed in 8875s and 8877s, but I'm puzzled by the mechanism. For gold melt
balls to be the cause, I figure that (a) they must be, and remain,
negatively charged and (b) they must be repelled more by gold wires with -ve
charge than whatever is on the inside of the anode with the same -ve charge
on it. I find both of these counter intuitive - am I missing something?
