Well I finally had to take two amps in. One is under warranty (Thank God) and the other is a TSL122. It was jumping (drifting) out of the correct bias range. I hope before I get it back, the tech checks it out in all three modes. He is supposed to be a great tube amp technician. Man I hope so.
I guess you get to call your guy up and ask, "WTF?"
I hope it gets rectified quickly and painlessly.
