Re: Tried to recap a tube receiver, and failed.

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..

Sounds like you got an electrolytic cap in backward. They are polarity sensitive.
