Questions about Bryston 7B-ST

Why do you shut it down?

I agree with Pbb. But also since you are covered by a 20 year warranty issued by a company that is known for their outstanding customer support and service, why don't you call or e-mail Bryston? You can find their contact information at BRYSTON.CA. Their USA service facility is in Vermont.

I am shutting down when not in use, because the mains change everytime in my area. I measure it sometimes 190V sometimes 240V.

I think its guarantie is invalid beacuse it had been opened and serviced by unauthorized service before i buy.

Our salesman says that amp sent to Bryston and they can understand if it was serviced by unauthorized service. if this happened you will pay all the costs including shipping to and from Canada. I am from Turkiye.

Hello Ozanhan,

I have owned 5 Bryston 7B-ST's, and am down to just one after breaking up the H/T set-up. I only powered mine down during thunder storms, or prior to going out of town.

The what you call weird, "zip zip zip" sound is normal after you walk a few steps away from the unit. The sound kinda sounds like when forwarding the film like a Minox 16mm spy camera. It isn't audioblely disturbing unless your ear in on the unit, I guess?

With the 7b-st's running for 6-8 hours steady, they should only be warm to the touch when setting your hand on the top plate. It shouldn't be hot enough to burn you?

I'm sorry I never spent quality time fondling the 7b-st's, to get to know their cold, warm, & hot regions?
