Yep, that would be them, alright. I forgot to mention in the first pass that obviously tube rolling plays a big roll. I had (and have) TJ meshplate 2A3's. I preferred them to the Valve Arts and Sovteks. A pair of ancient RCA's were lovely till one got feeble; that's when the meshies came on board.At that show I had one dead and one live input/driver tube. (One didn't enjoy the drive to Toledo.)
