UPDATE: Apparently it's the pot and assembly used for the live outs. The part isn't off-the-shelf and has to come from Mesa; I took a quick peek at the guts of the replacement unit before I took it back, and the replacement pot in my unit appears to be different. My unit was still under warranty, so no idea if this is something they'd replace free or not.

Rec Pre owners-- have you had a problem with unbalanced output from the live outputs?
I've now encountered this problem with two different units.
My Rec Pre has been sitting in a repair depot in Toronto "waiting for a part from Mesa" for ten weeks now, and the replacement unit the vendor gave me has the same problem, though not as bad. On mine the volume pot basically didn't work at all on the right channel, it seemed to be stuck at about 70 per cent volume; on the replacement I have, they both respond to the pot but the right channel is about 6Db quieter than the left. I hadn't noticed because I've only had the replacement for a week and had been using it mono into my MkIII instead of my stereo power amp. I noticed real quick because one side drives the 20/20 into clip and the other doesn't!
I've tried several different new and old balanced and unbalanced tubes, 12AX7 and 12AT7, in V6 and the problem's the same. The recording outs seem to work fine.
I'm going to call Mesa about this on Monday, but I'd like to know if anyone else has noticed it.
