[sdiy] Damned amplifier

[mark verbos]

today my stereo amplifier developed the same problem!

sounds like crackling on the left side. I took it apart, cleaned it. the 
problem was gone. I put it all back together, then 5 minutes later it 
returned!!!!!

I'm open to ideas. I thought maybe the caps in the power supply were 
dead. Am I crazy?
