MeanMan -
There is a group buy for F3 pcb boards at the below link, The F3 being a very close relative of the Zen V9. You may want to it out.

Adjust R3
I couldn't find the post, but I did find the information in the ZV9 article on www.passdiy.com - page 9 of 10 in the following:

As yet another alternative if you don’t want to test the devices, I recommend that you simply select R3 so that the Vds of the JFET in the amplifier is 2.5 volts with the output DC figure of 23 volts. More often than not, this is close to the sweet spot.
