I just bought a used bryston 4b it is about 21 yrs old ,Bryston installed a new power switch ,was wondering if they do a complete overhaul on it when they get it back to the factory, i paid 750 for it ,also should i leave it on or turn i off when not in use, because i have a bryston 2b that i left on all the time and it didnt get hot ,the 4b stays warm, iam running psb stratus golds with the bryston 4b ,is it possible to bridge the 2 of them or do i really need to ,thx thats allot of questions
