OK, I swapped out the BAT for an ARC SP9MkII I have hung onto for an office system (glad I didn't sell it to help finance the Vandy 3a sigs I've been lusting after). Everything is fine now, so it seems to be in the BAT line stage somewhere. I will put it back in and check all of the line inputs. Unfortunately, there is some kind of imbalance in my listening room that tilts the balance somewhat, and there IS some crosstalk into the dead channel. These factors complicate things. The ARC has a balance control which I do have to tilt over slightly; the BAT does not. I'll report back later- any new thoughts greatly appreciated.
One channel pre dead, one source only
I've only got one channel live when I use FM. It swaps when I swap the FM outputs, so it appears to be in the pre (BAT VK3i). Seems kind of wierd that only one input is involved. My nearest BAT dealer is a 1.5 hr ride away, so I'd like to have some clue before I bring it to an independent technician. I will email BAT after the holiday weekend, but wanted to know if any of you folks have any ideas?
