When Papa presented this to the community about 5yr ago there was (for some unknown reason) little interest in it.
I asked Didiet78 to lay out a board and he did, it's beautiful and fits the UMS, found here - http://www.diyaudio.com/forums/pass-labs/227503-ab100-class-ab-power-amplifier-3.html#post3497315
And still the community didn't respond with much more than a murmur.
SO, here we are some years later, this is still a really neat design, and would be a great candidate for a diyAudio Store project. I'd be more than willing to do the prototyping and guides if there is interest, may we have a show of hands?

LOL.
Degeneration is not the only way to improve the linearity of a long tail pair. It can also be done by increasing the tail current.
From the looks of the current sink transistor choice this might be what's done.
