Perhaps your tubes were from a different manufacturer, and probably a different manufacturing process. Since they are from 1984 to 1987, that's even more likely.
My IN-1 tubes are from the Anod plant, and have date code of 1992. Each tube was displaying a single numeral 24/7, with no cycling, dimming, multiplexing, etc. I had failures every few days. Each failure was a micro-filament that developed between adjacent cathodes, causing an electrical short between them. After switching to Burroughs tubes, I've had only 1 failure with 15 tubes after 2 years. That failure appears to be a broken internal spot-weld. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
