I recieved this amp a few days ago and it has a strange problem with one of the channels. when i tried to run it i a bridge mode, it reported distortion at 10V rms via o-scope, in stereo mode, one channel has 18V rms, and the second one has 8.9V rms before it starts to distort badly. All this was tested on 4 ohm subwoofer. I took it to my repair guy, but he is unable to detect what's wrong. Can somebody help me with this? He told me that he checked all transistors and capacitors and everything seems ok, but the resistors cannot check because he does not know their values. Is there any schematic for this amp?

How to check that and were i can adjust that? I forgot to mention, i noticed all that when i was trying to set gain, so i used sine wave at 40hz. Also when there is no speakers connected to the amp, i dont have any distortion up to 42V rms in bridge mode.
