On a related note, I'm running it with two 1x12 Orange cabs, the PPC112s, and it seems to me that they are fine at low volumes, but when I get the volume up around 10 o'clock on one of the drive channels, the high end gets cranky and harsh. What I am trying to figure out if that is a function of the space (an underground basement with the cabs practically against a wall and pretty much in a corner), the Vintage 30s in the cabs, or the cabs themselves. 6L6s are supposed to be smooth, so I don't think it's that, and even turning the treble and presence controls all the way down doesn't get rid of the harsh bite, so I am inclined to think it is related to the cab. I also have a Peavey Windsor 4x12 and I could load the V30s into that for an oversized 2x12 (I'm not even considering the POS Peavey speakers), but then I would have to haul that huge cab to gigs and I really don't want to do that...
