I think I may have documented it on ARF, but if I didn't I'll have to comb through the unreleased YouTube video footage I recorded on that project later.

I saw it. Well done. But I'm not interested (or good enough?) to tweak out a circuit to match the DuMont.

I believe Bob Anderson did. Maybe he can chime in.
