I'm working on a K200 frank (6 transistor with reverb/tremolo).
I've gone through the output section and its working fine. I went through the pre amp board and independently they both work great. Here's my dilema, I get a distorted signal if I run the 2 output wires of the pre amps together. I have another amp (595 with no effects) and using it as a clone I add in the resistor R146 on PC 101 to connect the 2 pre amp signals together and the output at the gray wire is distorted. Again I have a clean signal from both channels seperatlly but they distort if I combine them? Anyone got any clues as to what to do?
