For trade: scarce early
tennis ball shaped radio tube, circa early 1920s, thought to either a Vac-O-Bub or The Leader brand. Filament open but in great physical displayable condition.
I'm looking for similar early 1920s radio tubes- working condition not necessarily important to me.
Collect misc. transmitting tubes? I have many oddballs
available here.
