Questions about Bryston 7B-ST


Hello Guys,

I have just bought a pair of 7B-ST,second hand. I have a few questions in my mind.

1- Amps sometimes produce a weird "zip zip zip" sound when shutting down only on parallel mode. It is not so loud but embrassing. It sounds like an exotic bird. :)

2- Back side and front side transistors are cooler then the middle transistor blocks.

3- It is written 6B on the outrigger boards of all channels.

Are these things normal?

Speakers; B&W M802 S3

Thank you

Best regards

Ozan

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.
