[neonixie-l] Re: Nixie Clock - Time Cycle enough to protect against cathode poisoning? Without slot machine effect
I just rotated the 15 tubes in my big clock after 11 months. They display the same numeral 24/7, which I believe is the worst-case scenario for cathode poisoning. 12 tubes showed no signs of degradation 3 tubes showed slight degradation: - A slightly dim tube is now fine after running 12 hours at nominal current - A slightly dimmer tube is better after 12 hours at nominal current, but not quite healed. Perhaps it will take a few days - Lastly, a '2' was not illuminating at the center. After 12 hours, it's fully illuminated, though slightly dimmer I did not check all digits for each tube; I simply rotated them to their next position. So it is possible that other digits are damaged. After the above 3 tubes have settled-in, I will do a thorough check of all cathodes. Conclusion ? Cathode poisoning definitely happens, though it seems to take quite awhile. It also appears to be reversible as long as it was not severe. I'll post an update in a few weeks when I do thorough testing. -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Re: [neonixie-l] Re: Nixie Clock - Time Cycle enough to protect against cathode poisoning? Without slot machine effect
Hi guys, is there anyone here having a tube with cathode poisoning that is so severe that cant be healed? It should be a bare metal depositing on the cathodes, so I am very confused why it cannot be healed? What kind of tube it is? I am now making a small research on aging new tubes just after manufacture (it was also used in original, industrially made tubes). They have pretty dirty (not visible) cathodes, covered by oxides and other residues, and I dont have any problem to make work every cathode. When the tube is new, it has pretty non-uniform glow, I think worse than cathode poisoning, but after aging process, it works like a charm. I use now 7 hours per cathode at 15mA, 50mm digits.

Re: [neonixie-l] Re: Nixie Clock - Time Cycle enough to protect against cathode poisoning? Without slot machine effect
I have a few Burroughs 5031 tubes that appear to be poisoned on some digits, and have not responded to attempts to restore them with higher-than-normal current. The glass is darkened on the inside, which I assume is deposited metal. Cathodes are still visible. -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Re: [neonixie-l] Re: Nixie Clock - Time Cycle enough to protect against cathode poisoning? Without slot machine effect
I have a couple of Z566 tubes that appear to be badly poisoned...partial illumination on some digits and noticeable flickering on some others..haven't got around to burning them off yet...Also a few IN-18's tubes with bad cathode poisoning too...

[neonixie-l] Re: Nixie Clock - Time Cycle enough to protect against cathode poisoning? Without slot machine effect
I'm curious as well. I could see issues with the 10's position for seconds and minutes, as the highest number it will ever see is 5. Is that an issue if you don't care about the other numbers? 10's of hours will only see a 1 for a 12-hour clock, and up to 2 for a 24-hour clock. Do we actually care about these other numbers?

If your tubes are socketed, you can rotate them yearly. It's a bit of a pain if you have several clocks (grrr...I have 5 clocks, and one of them has 15 tubes) -- You received this message because you are subscribed to the Google Groups neonixie-l group.
