AMP looks good, but does not make sound.
When I first plugged it in it made sound, but sounded very distorted; barely corresponding to the input signal
Then it only made a slight hum
And now it does not make any sound, except when I unplugged it it pops a little
It looks good, where to begin testing or repairing it?
I'm not good at repairing these things, but sometimes I get lucky and it is usually because some one had the same problem and fixed it and told me how to do it
I recently tried to fix a Velodyne micorvee subwoofer and gave up after changing a lot of the caps I think I only had two "chips" to replace, but just gave up. I think I messed up the board a little trying to fix it

Likely a blown drive amp and one or both downconverters. Not an easy fix. This is a hazardous amp to work on.
