Problem with Bryston 4B SST.

I sent both amps in to Bryston, one had a loose connection according to them. They Tightened it up and the other one has the slight vibration on the starting circuit and they said we can't do anything about that!  The note says it shutters! Cost me almost 400 for shipping. When I go to move up the line A prospective buyer will probably not buy the amps now. Thanks Bryston 

I never said the cost of shipping had anything to do with Bryston, Bryston didn't charge me anything and sent the one amp back saying there is nothing we can do, (left the shuttering problem alone) They made sure they were both up to spec though  

 

When I Asked mike picket about it, I didn't get an answer! Now The amps play just fine but I wanted it fixed so I can possibly sell or trade them when I move up to the 28's, so far I haven't found a dealer to take these in on trade, they want cold hard cash.  I can show anyone the note from Mike Picket pertaining to the shuttering as not being a problem but most would have a problem with there gear making noise like  that.

Man one of my 7b sst2 smelled like an electrical fire. The lights inside where flashing red, normally there green.  I had to reset it. Once back on the front light went green and red maybe orange I don't remember. The top was warmer than the other amp and I wasn't running them hard. Shut it down and pulled from service. What do you think, send it in? I've put another amp in there place. 

This one monoblock in question has always ran 10 degrees hotter than the other. Not until I moved my rack did it mess up completely though. I'm using another amp and it's not having a problem. 

He must've replaced the caps and got it back to spec for 240, think they'd go that much for just a cord?
