New here. I'm having a problem with channel 2 (dirty channel) no sound at all. Clean channel is fine. If I run my gt1000 in the return it's all good. I swapped all the preamp tubes around 1 at a time, still no sound. I did the tapping on the power tubes, no sound or noise. I ordered all new tubes. (Everything is back order.) I'm a noob sorry, I tried searching.

Thanks in advance.
 
Hi did you sub the preamp tube with a known good one or just move around the ones you have?
 
You may want to open her up and check to make sure the ribbon cords are properly seated.
 
I might need to do that, but I just purchased 4 new power tubes, and 2 new preamp tubes. Will see tomorrow night.
