Turning my XTC Green Ch into a Helios 70's/Plex


New member
I know the Green Channel is based on a Super Reverb so the component values are different but I wonder if it's doable with how it shares preamp valves. Probably not but it would make this my perfect rock amp. I don't see a lot of activity on the Bogner website so they may not do mods to the XTC any longer.

All a xtc is basically is 3 different gain stages mainly. Put be-od or a vfe pedal on the first channel and its a 4 channel
