I picked up this amp a couple of years ago and it has worked pretty well for me until now. I hadn't played it in a while and for some reason the distortion channel doesn't seem to be working. It still takes some warm up time for the distortion channel to kick in but there really isn't any distortion. On top of that there seems to be some odd feedback.
I have never repaired an amp before, but I am a computer engineer with a descent circuits background. I have done a some analog design and signal processing. I am trying to find a schematic for this amp, but have come up short. Does anyone know where it can be found? I found some for the roc pro series which seem similar to the board in the 650 but not exactly the same. Thanks
