i buy a used mesa 50/50 power amp (the old model) that was made in 1998 i think. The guy that sell tell me that never change tubes, and he not play too much it. I check the amp, and tubes looks to be good (sounds great) but have a little problem that i think it is not the tubes becouse the unit have a problem with the ground (when the ground switch at rear panel is on the amp make a big hum-buzz noise without any other unit in the rack, switch off, no noise at all). At 10-15 minutes of playing begins a very little noise "ssssccccrrrriiiiccchhhh" an another ones like radio.
I think i have to retube the amp becouse 8 years is so much, but the ground noise i thing dont go away with the new tubes.
Anybody nkows a good page that sell mesa tubes cheap for my amp?
Thank you
