I had an original Bryston 4B which developed a mechanical buzz in one the transformers. Since Bryston was within an hours drive, I drove the amp to their factory. I was brought into the repair area where the tech removed the cover and said that Bryston now used the new toroidal transformer in their amps.
They asked if I would you like to change out both transformers for the new toroidal ones. I asked how much, and they said no charge. They did the full upgrade while I waited and benched test the amp to ensure it exceeds factory specs. Great company!
