Hello Paul,

Please thank Jim Williams for passing along his test schematic and
post it here along with your own test circuits (or just email them
to me if size or format is an issue and I'll be happy to post them
for you over on alt.binaries.schematics.electronic). It's been a
few days now. Should we expect them tomorrow? ;)
