Can anyone tell me what happened?


My tuner was on. My preamp (anthem AVM-30) was on and set to a selection which has nothing attached to its in or out terminals. My amp (Cary/AES 2A3 SE-1) was on. I replaced the 6SN7 tubes last evening in the amp. Everything played beautifully last night.

The system was left in this "on but no load" mode as I do sometimes when I leave the room for a few minutes.

I returned to a deafening hum coming from the speakers and smoke coming from the preamp/processor. Turned everything off and let it all cool down.

It is playing now without problems except that the music is lifeless.

What could have happened???

Any ideas will be greatly appreciated.

Thanks

Did you disconnect and reconnect any interconnects? I once left and came back to a big noise like that, no smoke though, but both of the interconnects were just the teeny-tiniest amount from being totally inserted and it caused it to go into this mode. No permanent damage but very scary.
