My guess is that the caps are fine. One of the switches on the front is the likely culprit. Move the switches back and forth and see if the sound crackles. If you find the one, use a cleaner like Rat Shack zero residue cleaner or a Caig product, or CRC. This should do it. Caps do not go bad often. If they go bad, they usually leak a yellow hard goo on the board. Replace quickly. This is an acid and will ruiin the board over time.
Tube amplifier bad caps
Hey,
My integrated tube amp has been experiencing the symptoms of bad filter capacitors. Crackling in my amp is so bad on both channels that I'm afraid ALL of the filter caps will have to be replaced. Tube swapping and tightening the socket pins has had no effect so I'm lead to believe bad caps are the problem.
A pic similiar to the inside of my amp can be found here. Are the can caps or the axial caps what I should be looking at replacing? I'm confident I can do the repairs myself (purchasing caps, discharging old caps, soldering, etc.) since I'm afraid of what the price tag might be for such a repair by a professional repair shop.
