Is there a site that will explain the codes on capacitors? I am specifically interested in finding out codes on asian made electrolytic caps. Thanks!

Axtman,
May not be specifically what you're after, but theres a fair bit of useful info on this site;
Badcaps.net - Badcaps Home
Although primarily dealing with electrolytics used in PC motherboard manufacture, many of the same manufacturers make caps of varying styles and sizes for use in other kit - I've certainly seen the same 'makes' in amps that I've seen in HP Compaq servers....
Hope that helps in some way....

The main thing to know is unless otherwise noted by a decimal pout or some other symbol, cap values are often shown in picofarads - pf. SO when you see a number on a cap like 223 or 104, consider it like a resistor color code: value, value, multiplier. Multiplier is the same thing as number of zeroes.
So 223 means 2-2-000pf, 22,000pf, which is the same as .022uf. And a 104 would mean 1-0-0000, or 100,000pf, which is the same as .1uf.Education is what you're left with after you have forgotten what you have learned.

Mr. Creeper,
You read my mind. I did come across some bulging asian electrolytic capacitors in a modern bass tube. I replaced them and the hum went away. I should have upped the capacity from 100 uf to 220 uf to give the amp more "guts".
