I run my IN-18's at 5mA, with pure DC. Each tube has it's own current-regulator so it's a constant 5mA regardless of tube-aging, power-supply variations, etc. Since my clock has only been in operation a few months, I have no reliability information. But it has 14 tubes, so it wont take as long to get that info as a 6-tube clock.
Going over 6mA would likely cause lifetime reduction. Using less then 4mA could risk poisoning according to some posts on this group. I've seen min & max current values on other datasheets, notably Burroughs, so I use the typical value (if specified), otherwise the average of min & max. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
