Found myself constantly tapping my phone for the time, or asking Alexa, so I sprung a whole 60 bucks (eBay) for a glass-tube neon clock for the gameroom. Red on the outside, and white neon on the inner ring. Simple, easy to read, and looks pretty cool with all the other neons in there!

I was downstairs playing a few games when I smelled something weird. It was a faint burning smell, but hard to find something to compare it to. The odor eventually dissipated but several minutes later I found my aviation gasoline sign was out. After a few switch flicks, the sign would flash “on” for a nanosecond each time, but wouldn’t hold. A closer inspection revealed this piece was melted. I wiggled it very gently and felt a slight “snap”. Clearly the glass tube was so fragile in this spot that little effort caused the tube/wire junction to snap off. Might anyone who has any expertise with these things give me an idea of what might have happened here and/or why it melted?? Thanks!

I'd guess the thin wire into the glass tube was cracked or something and arcing, which melted the rubber boot. And eventually what was left of it or the thin wire broke off.
LTG : )
Quoted from Coyote:Yeah, the wire leading to the electrode, in the glass, can be thin and/or low quality. (Since they're not really supposed to move that often, if at all!) So over time, vibrations or other causes can cause the wire to overheat and break, like a fuse. In Cirqus Voltaire, vibrations can often cause the wire to shear off where it enters the glass as well.
Likely it's been getting hot for a while, and finally really took off as strands started breaking (increasing resistance, increasing heat), and finally breaking connection. :/ The glass broken there also looks like a bad weld - glass wasn't flowed properly from the electrode to the tube, and it snapped.
Appreciate the feedback, thank you. Do y’all think something like this is easily repairable, given I can find someone who specializes in that?? The piece isn’t old, nor was it expensive, but after a 30 year career in aviation, it has some sentimental value.
