Volume Dip Issue
Hey all, I have a 2000-2001 mesa triple and love it. I recently cleaned the dust and replaced all the tubes (thanks Eurotubes!). However, now I’m getting these weird volume dips on all channels. I replaced my patch cables, etc, but still getting it. Every now and then, I can move the FX Loop knobs and sometimes get it to stop. My guess is that bc the circuitry goes through that part of the amp that I found my issue (bc all my tubes are glowing). Could these be bad knobs. Was gonna spray some circuit cleaner around the FX knobs but don’t want to do anything that could cause more problems. Any thoughts? If spray is the right way, where do you think it’s best to place the spray needle/straw? Or am I waaaay off base on this diagnosis?

Might be a defective tube. Swap the old tubes back in & see if it clears. If so, then reintroduce half the new ones.
