Yes Nelson Pass has released to the DIYers the schematic for the wonderful M-2 amp. See 6moons for reviews. There have been several boards made and put in group buys over on Diyaudio.com's Pass forum.

Just finished the M-2 this afternoon, I wont bore with Pics, it looks just like the F-6 I recently posted, same chassis/heatsinks, same power supply. What a wonderful amp!

you are a dynamo!
what is your favorite pass preamp? i just heard a bosoz (bride of son of zen) and was amazed. thinking about a new build after doing a simple B1.
 
This amp (M-2) just keeps getting better and better. Right now, I think it is my favorite. Compared to F-6 Both excel in detail retrieval, micro details of acoustic instruments and so forth, vast huge imaging, the M-2 doing it in a warmer way, not to be taken as too warm by any means, While the F-6 detail is a little the other direction, but again, not excessively so by any means. Both are low parts count amps that have a transformer in the mix. The F-6 more on the output, the M-2 using it for gain after the same J fets as the F-6, the M-2 configures them as buffer, F-6 for gain.

Tube folks, including SET guys, are loving the M-2...as 6moons reviewer said, its not about sounding like tubes, its about superiority....both he and I die hard tube enthusiasts previously! I haven't chased an exotic tube since the F-5 several years ago. Can hardly wait for the F-7 to sell in sufficient numbers that it's schematic is released. In the meant while I have the Pumpkin-Shunty to build and some speakers...
