I just discovered one of these tubes (labelled as a Dario ZM1050 / Z550M) in what looks like NOS condition. I heave read a lot about from from various sources such as: https://www.dos4ever.com/Z550M/Z550M.html and here http://www.tubebbs.com/tubedata/sheets/013/z/ZM1050.pdf and I note that several articles refer to driving them in normal 'Nixie' mode rather than using the 5V switching that they were designed to support.
Before I hook this up to the grid I wonder if anyone here can confirm voltages and anode resistor values that might stop me from frying the thing as I also read that they might be few and far between. >From various specs I have found they seem to suggest a supply voltage of 90V ac and a cathode current of around 3mA. I am insufficiently qualified to translate that to the 170v DC supply, strike and maintaining voltages (and hence series resistor values) that I am more comfortable with. The pinout shows a cathode, an anode and st0 - st9 and from what I can understand from the notes is seems that the original design concept was to drive st0 - st9 with 5V levels as high voltage transistors were not readily available at the time. Has anyone driven these in any way and if so, would they be able to provide some further insight? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
