I'm leaving the world of electrostats, and this is the last piece of that puzzle. Just need to downsize and going minimal as much as I can. Asking $1700 shipped and paypaled within the USA (international will be extra, depending on country)

Details from an August 2014 email from the legendary Birgir (aka spritzer) when I asked him about it:

"The mini KGSSHV. I have a waiting list for them until the end of this year but that one in the picture was the proof of concept unit and it is in the US already. I sent it to Justin for measurements and then it went on loan to (edited) waiting for a full size KGSSHV. That amp is now ready so it's time to sell the mini. As you can see on the front my laser guy moved the KGSSHV logo over one of the mounting holes but other than that it is built to the same spec as the 'production' units. It lacks the voltage selector and the solid aluminum feet found in the them plus it uses slightly cheaper output transistors due to lower voltage..."

This unit is beautiful and after the BHSE, was my favorite stat amp (small enough to take to local meets). Dimensions, in inches, are 11x9x4 (with 11 taking into account the volume knob).
