Hi guys, the other day I picked up a Carver PM 200 for $90, so I thought it might be good to run my Chorus' with. After waiting a few days to get XLR cables so I could hook it up and listen I cleaned out all of the dust and resoldered a transistor that had broken off the board, I fired it up and got a audible hum coming from the amp near the big blue caps or power transitor, I had great sound out of one channel and the other was getting a pulsing hum noise that sounded like trying to tune a radio or something, now the amp is is protect mode and making this pulsing sound.
Any Ideas? I would be fine with having to replace some caps or other components I just have no idead on where to start the diag process.
Thanks.
