One more question for you guys: what is min voltage rating for 5pF comp. cap, C1 & C2? Will 500V good enough?

Will this be the right tool to measure the bias voltage: http://www.fluke.com/fluke/auen/accessories/high-voltage-probes/80k-40.htm?PID=55357

Thanks. So it is safe to measure at the STAX socket without connecting the headphone? Even with signal feeding to the input? I want to make sure the amp is as close to 100% stable as possible, before connecting my headphone to it.

I'm in the middle of the KGSSHV build, my first electrostatic headphone amp. I have a question: how do I make a dummy load for the amp? do I need one for the initial adjustment? Thanks

I was considering about making another batch of bare boards. Anyone else want to join in?
