That link is not working but a search of the forum turned this thread up: https://groups.google.com/forum/#!searchin/neonixie-l/shorted$20segment|sort:date/neonixie-l/w4YmXnY9dgE/8o-AsZZyBQAJ
I assume that is the thread you were referring to. I'll have to give it a try. If the tube breaks then so be it. About all it is good for is making either an "A" (8 with bottom off) or "P" for an AM/PM indicator. 20+ years ago or so I stupidly cut off the pin for the #13 segment because it was shorted but it could be repaired and used again. Especially considering the value of the tubes it would be a minor inconvenience. I'll have to dig the tube out this weekend and give the repair process a shot.
