USAFA: Audigy 4 (roommate's computer) ---> DIY GB-150D-based integrated amp (stereo configuration, remote-controlled, power-on delay for output, and heavily class-A biased (3.9mA/channel) LM4562NAs used in preamp section) ---> Yamaha NS-527 (modified with Vifa 6 1/2" woofers, Panasonic film caps in crossover, and heftier internal wiring)
Ghey-C'97 (my piece-o-crap issued laptop) ---> PPAv2 (class-A biased AD8620 (2.5mA/channel), 8600uF pre-regulator, LM338 high-current regulator, 40mA/channel output bias) ---> Grado SR-225 (yes, I bring my headphones home from the Academy during leave)
It occurred to me recently that it has been nearly a year to the day since I first posted looking for an alternate source for the Millett Hybrid PCBs. And until today I've never built one for myself . I had a mostly finished amp that'd I started recently for no real reason other than the fact that I still have enough parts kicking around. So I set out earlier this week to finally build myself a Millett, even if it won't be the one that I end up with permanently, here are the results.
I like to think of it as pretty much as maxed a configuration that you can build in the smallest possible box. It runs a 24V AC wallwart into a TREAD running 28V DC into the amp. From there you've got all Cerafine and Silmic II caps feeding Tung Sol 12FK6's and diamond buffers all controlled by an alps pot. All housed in a hammond 1455T1602 (6.3 x 6.3 x 2.1") case. Sounds really good so far, and I think looks ok too.

I really like the way the amp looks. It has a simplistic, uncluttered look to it. I also like that plast (rubber?) ring you placed around the tubes. Overall, great job!

OK, out with it. Where did you get the Tung-Sols?
...Please...

Thanks Nate, your Millet preamp served as motivation for this build
Thaddy's amp was/is pretty sweet. What are your plans for its use as a preamp? My ultimate goal is to have a setup where I built 90% of the components. The only thing that I don't think is really practical to build is the transport although ideas have surfaced recently that make me think that might not be out of the question either . For now, I'm stuck with this...
