Hi all
I have a guitar amp that is brand new out of the box and I have a hell of a hum. So I called the manufacturer and told them and they sent me another unit, did not even want the original one back. <???>
Anyway, I wanted to see if I could fix this one. If I am not mistaken a 60 cycle hum comes from bad caps or am I wrong there? Been a while since I have been in electronics class.
I pulled the back and saw about 6 caps and am thinking of replacing all of them.
How can I test a cap to see if it is working properly?
Any suggestions?
Jim
