bought some of it as surplus from a commercial tube factory, maybe
circa 1920's..
I would have liked to have seen a bit more on the details of the
gettering and filament activation...

So, there ya go guys: it is only a small step from that little triode

Absolutely! That damn video clip is just sheer fun to watch! I'd love
to have a friend who made 'em in their basement!
