I tried to re-cap a tube receiver (amplifier + tuner), and now when I turn it
on it starts playing music for a few seconds after it warms up, then the music
fades out and and hum takes over. I don't really know what I'm doing, and the
wiring inside looks like a mess of spaghetti. I'm pretty sure I replaced the
caps properly, but I used .068uf WIMA caps to replace .050uf wax/paper caps,
and I'm wondering if the value difference, added up over 8 caps would make a
difference? Other than that, does anyone have any advice based on my
description of the unit's behavior? Any comments whatsoever might be helpful..
