Everything else was working fine except the pre. Like I said I have a dedicated 20 amp curcuit and regulator and I will give great credit to Hydro-Quebec as they do have one of the best sytems (supposedly!).
I turned it off this p.m. and just turned it on now and it worked as usual no problem! Strange but who knows? I will keep my eyes open for anything else unusual! I personally don't believe the unit itself has a problem so I am not worried and even if there is some sort of gremlin, I am still not worried as I will just pack it up and send it that is the advantage of Bryston!
