If at first you don't succeed, get a drill
A couple weeks ago, I went up to Boston to record the wonderful Julia Torgovitskaya aka juliatorgo at Tufts' exceptional new Distler Performance Hall in the Granoff Music Center. I use an incredibly simple, cheap and effective rig to record live to two which consists of 2 AKG C 414 B-XLS microphones, 1 Aphex 207D and an M Audio Microtrack. This allows for

Where did you get those condenser mics!!! They must make Yuliya sound awesome (and warm!)
My guess is either:
1) Vacuum tube going, replace in matched pairs (both stereo sides of the amp)
2) Static buildup in the chassis. Check the grounding circuits of the cables with an Ohm meter.
Btw, check the "fire-bottles" in the mic pre-amps too!! And make sure those are properly grounded as well!

As for your guesses, there is no amp here. There is only a single tube in the Aphex which is the mic pre. The static buildup theory is good thought though. I had swapped cables though.
The AKG C 414 B-XLSes are widely available. Most engineers dislike transparent gear because they primarily capture sound sources that sound like shit and therefore need a lot of help - i.e. Marshall stacks or singers who can't sing very well.
That hall was really out of control though as it was super wet (most halls are wetter when they are new). We need to record again so I can do it right now that I know the problems that are gonna come up in post.

Take a VTVM or similar and check the neutral-to-ground of the power receptacles your stuff is plugged into. If there is ANY resistance, then that is most likely the source of phantom static and/or electric charge of one type or another build-up in your equipment.
(as well as being incredibly unsafe for the performers, as well as tech staff)

I'm telling you, over volt caused excessive heat and a lack of ventilation exacerbated the problem.

Those FET's are really really sensitive and fragile electronically

I don't have a warranty as I got the unit second hand for a great price. Furthermore, they would probably be hesitant to service my now modded one :)
Have you not been sleeping or is something wrong? I don't mean that as an insult or to be rude or anything. You're just usually very on the ball and you seem to be very not on the ball in this thread and it has me somewhat concerned.

My philosophy is that we should do the things that only we can do. Anything else you should just pay someone to do. If I were in your situation, I would pay someone to clean the apartment, go grocery shopping and take care of the car. You don't need to borrow a car. You can just rent one. You need to write your article, work on your dissertation and tend to your fiancé.
Here's something to look forward to. When I move to Southern California, we'll hang out. OK? :)

But I may wind up in Camarillo (Mental "Health" Institution) by that time, if I don't deal successfully with this...

I finally got a lot of sleep last night - 10+ hours and am in much much better shape!
It was jet-lag, an awful awful brain wasting case of accumulated jet-lag!
I will be spending as much time outdoors as physically possible the next few days to reset the internal biorhythm clock...
I gotta figure out how to use the D-alpha-tocopherols to avoid this from happening the next time I travel across timezones. I've done it a million times before but it's never been this bad before!! I must be getting old(er).

For the longest time, I thought jet lag was a made up excuse for like being hung over until recently I learned that there is actually a purported cause for it.
I've never experienced any sort of jet lag. Then again, I used to not sleep so...
I am getting old though.
