Hey Chris I found this googling for 7800 stereo mods. Nice little review. Anyways, I would try removing the 47pf cap and the 680ohm resistor right below the 47pf cap. The 47pf cap is the orange one with the black on top. After that bridge the two contacts where the cap used to be. This might solve your color issue. Also, do you mind if I link this page to my website?
