The '4' in the unit-hours position I saw in the video should not have been poisoned during normal operation, because all 10 cathodes will get exercised. Could this tube have been in a different position, such as the 'tens hours', and been poisoned that way ?
What I'm wondering is if this is normal 'wear-and-tear' , or a small leak, rather than classic cathode poisoning (contamination of a seldom/never-used cathode from other cathodes that are used). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
