yes I kind of thought the power system might have gone haywire. It's convenient not to worry about sending a loud pulse through your amp, but it's more complex than a simple switch.
I couldn't and can't figure out how multiple lights could go on through what is supposed to be a switch. But while I understand mechanical switches, I don't really know about electronic switches. I wonder if something else got blown out by a power surge? I guess the only way to find out will be to get it looked at.
So for airtime: This was the biggest splurge of my audio life. It was among the top tier of preamps at the time, and I have continued to love it, even as, disconcertingly enough, every new audio research preamp is reviewed as a big step up, and it is now antiquated according to reviewers. Still, if I get it working, it's fine enough for me. And yes, I know expensive preamps eventually need expensive repairs...it's part of the deal...sadly there is never a good time for an expensive repair, but it's all part of life. We'll see what happens.
