Do you have a friend or relative with good basic electrical knowledge to whom you can turn for help ? If you are unsure of your skills, then don't attempt this. Also, the cans of the capacitors are going to be at line potential. They have plastic shrink labeling around them but there is still some bare metal exposed. You need to exercise care that these don't come into contact with anything else. Observe polarity of the caps and diodes. The caps usually have a (-) marking on the side with the negative lead to indicate polarity. The diodes have a band on one side to indicate the cathode (negative) side.
Amplifier hum - normal?
Is it normal for amps to emit a slight humming noise from the transformer when turned on?
I never noticed it in my old integrated that I lived with for over 10 years, but that was lower power. Now I've gone from 50wpc to 120wpc... don't know if that makes a difference here though.
I mean, it's not nearly enough to bother me or even really be audible past 3 feet away... but I am curious if this is typical for amplifiers to do this.
