Building the Audio Note Kit 1 SET amp...

Al,
There's a "+" sign on the PCB for the electrolytic cap positions and also the the band on the cap itself that shows you which lead is "-" so it's pretty hard to screw that part up. Doesn’t mean I couldn't have done so, but I think those are probably okay. Thanks for the detective work, though!

Just commenting to store this in my threads. As someone mentioned earlier, this is a quality group of commenters who do not feel the need to pull out genitals... and a compelling story.

Well, Friends, no joy just yet.
The technician, with guidance from Brian, was unable to troubleshoot the problem, even with the complement of new tubes.
So, Brian and I will Skype early next week to see if we can troubleshoot the issue in that way in real time.
If not, Brian's going to get the amp shipped to Digital Pete, the fellow in Florida who does assembly of certain ANK products for those who (like Roxy54) want to buy a kit preassembled at extra cost. (Roxy has the 10th Anniversary Edition of the Kit 1 with the AN Copper Foil caps and the C-Core trannies.)
Pete's a real artist. Some of his assembly work is featured on the ANK website and it's gorgeous. And if by some bizarre chance I got something like a bad transformer (which, given that they're all pretested before shipping, shouldn't be the case) he'll know and be able to swap it right there.
My hope, of course, is that Brian and I can figure this out on our own.
This seems to be one of those one-in-a-million things. Brian told me that he sold two Kit 1's not long after mine and they turned out perfectly. Go figure!
I'll keep y'all posted!

Rebbi good luck I hope this can be sorted out. I know it's frustrating when one doesn't know what the problem is. Thanks for timly update information as everyone is rooting for you.
