One of the IN-18s in my Nixichron has started to fail. I don't know if it's
cathode poisoning or some other failure mode.
In the 10's hours position, several of the digits are not lighting
completely, they are dark toward the bottom of the tube, probably the
bottom 1/3 of the numeral.

This is an issue that is most obvious on clocks with lots of
functionality. If there are different modes/menus that display numerals
on a tube that are not normally lit as part of the clock, then you'll
see this. Best advice is to take full advantage of automated
cathode-poisoning prevention
You're all wrong, it's leaking gas through the pins.

Gene, please explain how you know this is the case.
Thanks

When you have a sudden performance issue, it's gas. Especially when large
sections of large-area cathodes go dim. Poisoning from sputtering affects small
sections and is observed over longer periods of time. I'll bet that tube will
start going pink soon.

Thanks Gene -- I'll keep an eye on it and let you know.

Yep, this exactly happened to me. A tube suddenly started having problems
lighting some digits. Then eventually it stopped working altogether.
I caused it because I was swapping the tubes too much. The repeated
removal/insertions caused the tube to leak at the pins.
I still want to rotate
