Let me throw in that while I haven't used Anders exact circuit, I have been
using a circuit of my own that does the same thing. So far it gives the best
"vector stability" of any of my experiments.

Anders circuit is easier to install, and the performance should be close (if not
exactly) identical in it's regulation.

If Anders is going to build up PCBs, I'm going to use his. I'm tired of hand
wiring these things up! (In fact I'm putting off fixing some WGs until I get
these from Anders, my work just got a lot easier!)

When you're close to getting these built, make sure you post to RGVAC, I know at
least Gaymond (I'm sure) is going to want a few of these...
