Hell to the group!
I need a few nixies for my vintage USM-207 counter.
They are the miniature 9-pin type, same size as a 12AU7, with red 0-9 arabic
figures 15 mm high.
Only thing I can read with certainty on the bottle is "Burroughs, USA".
Which type are they? Any idea where to find them?
Thanks,
Francesco Sartorello
