Geographically, that is a gap for me.
I would contact Steve at "The Service Department" in Bridgeport, CT. He is the national repair center for a lot of brands and is an ex Krell employee. I would be shocked if he can’t fix it. That being said, at that distance you may as well send it to Bryston.
The other that could be better in terms shipping is Deltronics in Chicago. They have done some work for me and are the service center for Naim and Musical Fidelity. Again, I would be shocked if they have not worked on and are comfortable with Bryston.
