@Jeff The heating should only be enough to prevent cathode poisoning starting with a healthy(ideally new) tube. I seriously doubt it would do anything to fix already existing cathode poisoning. It's driven using the same, standard current(4-6mA for an IN-18) for normal operation. To fix existing cathode poisoning you do indeed have to seriously overdrive the tube and keep every cathode needed on, sequentially.
@Allen I made this with the intent of running it more often - a few seconds every 5, 10, maybe 15 minutes. If cycling on every digit change, it could be quite distracting, because the perceived brightness of the tube increases dramatically, and it would just keep flashing. Doing it every 30 to 60 seconds should be about the minimum time period acceptable, but it really depends on your tastes. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
