I laid out a through-hole version of Warren's board in Eagle and had OSHPARK fab up three of them. I sent one to Warren and am using the other two. The one mod I made was to use a single darlington TO-220 instead of the two transistor stage that Warren used. They seem to work quite well.
I started another layout to use '723 regulators for the supplies and an external EFC voltage generator, but never got around to finishing it.
