Brando: I meant to say that all of the numerals inside of a single IN-18 tube in the H[X]:MM:SS position did the same thing as you described. My cathodes in the bad tube faded out from the top over a period of about a week or less and the failure began with little warning after operating perfectly since the initial power up of the clock. I was also running the cathode poisoning prevention. Have not had an issue with other tubes in other location of the same clock and I got about 2 years out of the first failed tube before replacing with no issues noted on any other tubes.
----------------- I recently had the same failure experience with a IN-18 in a Blue Dream. The digits also faded over a period of a little less than a week until no digits worked. I posted my experience and the general conclusion was that the way the digits faded was indicative of a failed pin seal. Are your tubes all from a particular date code range? It really doesn't sound like a clock failure due to the equal failure of all digits. What tubes and clock do you have? Jeff From: [email protected] [mailto:[email protected]] On Behalf Of Brando L Sent: Monday, August 15, 2016 10:33 PM To: neonixie-l Subject: [neonixie-l] One slot on my clock keeps burning out tubes, while the others have been good for years. Thoughts? Had a question for you guys, would be curious to see if anyone has seen this too. I've had a nixie tube clock for 3+ years and for some reason I've only had to replace the tube in one of the digits, but I've replaced it 2 times and now about to do it again for the third. Since this is starting to look like a pattern and my other tubes have had no issues, I'm thinking it's not the tubes fault. It's the hour position on the clock where X is: HX:MM:SS. When the tube goes, it's like a 1-2 week death; slowly bits of the digits aren't visible, and then less and less until it is digit less. What's the best way to diagnose? Much Appreciated. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
