Bifwynne,
The speaker cables are the Anti-Cables (solid core copper with a thin layer of coating) with bare ends so switching L and R would most likely not show anything.
I checked the tubes and the bias was spot on. They are relatively knew as I replaced them in late July. I'm of course talking about the power tubes in the monoblocks. I don't know how to check the input tubes in the power amps and the tubes in the line stage. Those are over year and a half old.
I might contact Rogue Audio to get Mark's input on the tubes. In the meantime, I'll follow Al's advice, which is always a good idea :) Thanks again for the suggestions; I'm pretty bummed about this.
