Hey the#9, welcome to the VintageAmpeg.com forums!
The GV-22 is an awesome amp. I like to think of it as the big brother to the gemini-1 which is my favorite amp. I was surprised the first time I played one because I wasn't expecting it to be as clean as it was. The G12 tends to break up a little more. I still drool over ever GV-22 I see them at guitar shops. I do have the guts from one that went through a fire. maybe some day I"ll piece one tougher.
anyway... have you tried simply swapping the preamp tube for channel 1? it would be the fifth tube from the left, when looking at the amp from behind. i.e. the first tube would be a 6L6, second another 6L6 then a 7199, followed by a 12ax7 (for channel 2) and the fifth tube would be the 12ax7 for channel 1.
