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?
