Hi TC,I purchased her in 2006,2 and a half yrs.old,my 4B-sst was shut off also
she's good.One of those things I guess.
When i powered up the 7B-sst,I installed bryston cables and for sure I checked
red to red ect.So when I heard her start to tick

,I shut her off and puller her out,checked again SLOWLY(same hookup).Fired her up T,T,T,POOF,instant rag doll

.,

.i checked again to be sure and still can't figure out why she did that,But bryston came thru with flying colours

..
