Bryston 4b bias on one channel won't go lower than 14 mv.
I have a bryston 4B that will not bias correctly. Even with the adjustment pot pinned down to zero it measures 14 mv. It needs to be between 4-6 mv.
Does anyone have any ideas what I should check. I checked the pot and it seems to be functioning correctly with the ohm meter.

I have not. I was hoping to find someone who works on these that might be able to give me some insight into diagnosing the issue. The amp is one of the original ones. Definitely out of warrantee and way to heavy to ship in to them.
