I am working on a kustom k200b4 that has a serious white noise problem coming out of channel 2. Very little signal gets through to the power amp stage. I believe that the power amp stage functions just fine and the problem is in the PC102 preamp board. Channel 1 is PC303 and the PA is PC703. I would appreciate it if someone would share schematics and some insight on this problem (now that I have posted this in the correct place).
