Problem with Quad II Classic


Just set up my new pair of Quad II Classic mono amps, with NOS tubes, and after one day of great listening, this morning I heard a hum out of the right speaker. When I looked at the amp, there was smoke or steam coming out of the amp, right around one of the Tung Sol KT-66's. Obviously I shut everything down and the Quad is going to make a trip to the shop--but anybody know what could have gone wrong? I dare not unscrew the bottom plate for all the dire warnings (in BIG print with lightning bolts around the text). Sob.

Oh yes--I had the amps (and my other gear) plugged into a BPT-2 power block. Could these amps not like that balanced power thing?
