[sdiy] cap autopsy

[Alex Dickey]

so as i prepare to replace the caps in this tube amp that i was asking
about, it occurred to me to ask a different question about the
performance/death of said amp.

when i first got the amp two years ago (at the flea) it worked.  over time
it slowly lost volume until it stoppped passing signal at all.  i wrote it
off as dead and stuck it in my friend's gear closet.  over christmas, i
found the amp again and for kicks plugged it in.  lo! it worked.  but over
the course of a few weeks of steady use, it stopped working again.

i have no doubt that the fact that the caps are TOAST is a big part of this.
but what's actually happening?  why does the amp work, then not, then work,
then...
