I'll venture a studied opinion and say that Nik has formally incorporated some of the changes that were offered here in early summer based on the Ayan/Lerner/Zucker mods and subsequent discussions.
When comparing the April 1 rev to the August 26th revision I stopped counting after seeing no fewer then a dozen tweaks.

A dozen changes
? what are talkin about?
There are only
two changes in the august version compared to the may version!!
A: decreased snubbercaps on V2 from 390pf in may to 330 pf in august
B: decreased resistor value in the PSU the 3K9/2W has been reduced to 3K3/2W increasing PWR line plate voltages.
No big changes - and not important changes as well - Check the tweaks in the forum to see some of the important mods.
