Repurposing partly faulty tubes

[Yohan Park]

I had this IN-8 that had the "2" digit not working well.
When replacing it I was thinking it would be a shame to throw it away. I mean, it's still working for a large part.
So I then got the idea to treat it just like a regular neon indicator and connect it directly to mains (230V), only using an anode resistor. I always had this idea in my head to make a neon night light and this seems to fit in quite well.
I think using digit 1 looks best but of course you can use any digit (or digits, just make sure the resistor can handle it). The AC current makes the anode glow as well which is just what I wanted. But if you want to just light up 1 digit or the anode mesh you can use a bridge rectifier of course. For me it's okay like this.
Time to make build a nice case around it!
(the picture doesn't really do it justice)

You might be able to de-poison the '2' by running higher current on it for a few hours.

Thanks for the tip but already tried, no luck 😊
