Maybe someone can answer a computer-tube question for me?
I have a large number of 5963 tubes (computer-rated 12AU7s) which I am
told "have gold-plated grids to guard against 'sleeping sickness' when
used as flip-flops".
My question: what is this "sleeping sickness"? Does this relate to the
long-periods-at-cutoff mentioned earlier on in this thread? How does
having gold-plated grids help this?
TIA,
Ed.
