I guess I was lucky, I got the mapleshade on and later off with no ill effect... but it is kind of a kluge with the grounding strap etc
since then I have learned (through reading the commentary of my learned compatriots here and inmates at the asylum) that a touch of microphonics is actually what contributes to the illusion of "air". in other words, too much damping is maybe a bad thing.
i have also proved to my own satisfaction that the only way to fix a truly microphonic tube is to replace it with another one...
I have had good luck with Herbies - the tube dampers and lots of other stuff - mostly I can't hear a thing but I figure its all cumulative and indeed I am sometimes thrilled by the way my system sounds
