Good news! Production boards have arrived...Top side:
Bottom side:
I got busy tonight and built one to test. Works great! It's not cased up yet so I didn't run anything extensive, but the circuit is well behaved, with no turn-on or turn off pop. DC offset is within ~0.7mV, I biased the output stage to 30mA, let it warm up, re-adjusted the bias several times and then gave it a listen. I don't like using audiophile language to describe it, but suffice to say that it sounds very good.
The PCB group buy will end in about 1 hour as I write this, and I will start sending out Paypal bills to those on the list shortly after.
I am also working on a website for this amp similar to my other project sites. Hopefully by the time you all receive your boards the site will be ready.
