I have been making numitron projects. Namely Bitcoin tickers that run a live stream of the price (tubes constantly changing digits since the prices changes 24 hours a day by the second). So, well over 2000 tubes out there and I offer free repair/warranty meaning people are apt to contact me if there was a problem. They run 24 hours a day.
I would say that I have replaced about 15 power supplies (USB). And, over that time, I have had to replace 4 tubes (3 customers) as a segment or two have stopped working. That said, I have probably replaced a total of about 20 tubes, but those other ~16 were damaged (destroyed) in shipping. Lastly, I run no cross-fading or ramp up/down technique. All tubes are direct drive of either on or off switching. Hope that helps. Have a link and/or pics to your clock kit?

Hi Everybody, I seem to have enough IV-9 tubes to where I can produce a batch of 100 or so 6 digit numitron clocks. Thinking ESP32 powered like my last one (Thank you to all those who gave suggestions, the kit came out great!). I'm thinking maybe try for a full through-hole solder kit with some shift registers. I know nixies are more popular.. but anyone interested in a numitron clock kit? Oh, one question I do have, anyone have long term experience (ie, years?) running this particular tube? How do they fare? Thank you! Regards, -Moses -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
