Had the same problem a few days ago. Unfortunately, after pulling the plug and try to power the BP-17 up again, there was silence. No function anymore. First I thought it blew the fuse again, as it did it a few times, but this time the fuse was not blown. Have sent it over through the dealer to the Austrian sales department. Hopefully they or better the guys at Bryston can resolve it. Seems a little bit sensitive that little new 17er. Hope it gets rid of its childhood diseases, as it is a wonderful sounding pre-amp though.
