Is anyone out there familiar with it. I have one that is misbehaving. i haven't used it for awhile so can't really remember tha problem, probably low gain in one channel that doesn't follow tubes when they're swapped.
Anyway, I'm interested in opinions of the sonic quality versus the DIY Tube driver board mod. Maybe it makes sense to just put a new driver board and cap board in and get it ready for use in a biamp setup.
