I have only one dead IN-18 and the "pupik" looks OK. If it can be
repaired then count me in. But I guess that one of the pins leaked.

I have at least a dozen non-working IN-18 tubes, though none (that I
recall) have broken nippl
I think that particular tube may have had just an overly large nipple,
that's all..haven't had any problems with the other tubes in the clock after
removing them and replacing them (matching tube heights).

I have my one tube, that's it. I could go for having it filled with argon just

Nixie Gang,
Am I to assume that nobody on the list has IN-18s with broken nipples (judging
by the response)? Should we give it a few more days for folks to chime in?
To reiterate, I was hoping to get a pool of people, so that we could collect
all the damaged tubes and have one expert do some
The hole for the IN-18 exhaust tip is .250" diameter.

Sounds like that circuit board could use a revision to enlar
Great idea.
Ummm, I don't have any broken/gassed tubes anymore (since I took them
apart, etc), but I will be willing to take/buy some tubes that were filled with
a different gas (different color). I want purple or blue. :)
The only tube I have left (broken) is a B7971 (looks like it was

Wouldn't work too well either if it ever did get vacuum! :)
If you're going to the trouble of a gas refill, why not make it argon
rather than neon and get some unique purple nixies!
