Well, I'm almost 8 years late to the party. Does anyone have high resolution photos of the 6SL7 - 50 L6 - 35Z5 version of the component side of the chassis they would be willing to post or send to me? I have friends Lelani that needed almost all of the caps and resistors replaced. The amp was working, but limping before I replaced the components. Now I'm getting only motorboating with no guitar signal. I've been through the schematic posted within this thread but that is not helping me as I replaced same for same and did not do any of the changes noted in the revised schematic. I'm sure this is a matter of having one component in the wrong spot. Thank you very much!
