Further to my post - I did a little research and decided to give it a go. I connected the filament to a DC supply and increased the volts until a discernable glow was seen on the filaments - this was around 10V.
I took the easy route of using the same voltage to supply a grid and a cathode - and it worked! For maximum brightness and kindness to the display (those may be contradictory!) I would love to know the 'proper' drive method/voltages and whether or not it is absolutely necessary to use A/C on the filament. - Richard On Monday, 16 February 2026 at 08:11:29 UTC Richard Scales wrote: > Hello, > I am fortunate to have a few of these 20 character multi segment displays > and would like to drive them. > > These have come from Goetlib games machine displays where where are two of > them mounted on a board (for which I also have no data) and I have several > of these boards and I hope that the displays are OK. > > Can anyone point me towards any data sheets or perhaps suggest what the > filament, grid and segment voltages and currents might be? > > Should the filament be DC or AC? > > All pointers gleefully received - thank you. > > - Richard > > -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
