That's what it looks like from the pics at headamp. Note that the amp boards themselves have much more ground plane (and possibly power plane) usage on their layout than the V2 did (the V2 boards have virtually no ground plane in the amp section itself)... much more like the new Lite boards.
The PSU is hard to discern. I can't tell from the pics what is on the heatsinks, but I would assume the regulators are there. Therefore, no OPA548/541 opamps for the output stage. However, it does use discrete rectifiers (probably Stealth or MUR860s or some type of hexfred) whereas the V2 used packaged std. rectifiers. There does appear to be one or two pots on the PSU... if this base PCB is going to be used to offer Dynahi boards as well, the PSU has to be configurable as the Dynahi uses +/- 30V PSU vs. the +/- 16V for the Dynalo, also at a higher current capability.
