Go to my website, click pictures, then nixie tube.
Do you know how to use this nixie tube?
By connecting the filament to 3v and the grids and anodes to 12v, I can get it to glow.

Hi Star882
Sorry this isn't much help but I thought these things were called "Vacuum Fluorescent Displays", "VFD" for short, I always thought Nixies were thermionic valves that contained a series of shaped anodes; excited by around 90v DC to show the required numeric (a blast from the past).

Your 'VFD' is from an old video recorder? I wouldn't mind betting it has more than one grid (guess at 3, each covering a third of the display) and anode each terminal connected to one segment under each grid area, giving a sort of multiplexing to keep the number of terminals down.

There again --- I could be wrong ?

Nixies are not thermionic valves, they are cold cathode discharge tubes.
