Good tube tech in Milwaukee, WI?

Anybody have a recommendation?

I just finished my Audio Note Kits phono pre and, despite having built two other AN kits that worked beautifully, this one has a dead channel and I can't find the problem and am short on time.

I can send it up to Brian but thought I might try a local pro first. I have the schematic so this is probably a one-hour job for a good guy.
