those 2 units are the result of a pile of parts from hennyo.
The chassis however are new, and much more expensive than
the parmetal things. Fully machined front and back panels.
alpha pots. transformer is potted, not sure where birgir got that.
kgsshvk boards are not any cheaper than the previous version boards.
just physically smaller. more expensive actually if you populate
The kgsshvk amp board and the T2 are the only fully dc coupled
electrostatic amplifiers with active dc servos at the present time.
+/- 1 volt stability over time and temperature.
There does not seem to be a way to do the off board version with
servo without going multi layer. Or adding the servo on an additional board.
The k series power supply board can be partially populated
for a bit cheaper build.
i'm currently on a massive software job that is going to take
till January at the earliest. But I do plan on a standard punch
file for the standard parmetal chassis for the k series boards.
including the front and back panels.
