Hi all, I'm new to this group so I hope it's ok to post this here. I'm having trouble with my nixie clock slowly killing one of the IN-14 tubes. The full story is I bought a broken clock with the hopes of fixing it or salvaging the tubes. I couldn't fix it so I bought this clock board:
https://www.ebay.co.uk/itm/354407683845 (I think there are lots of identical ones from different Chinese sellers.) It worked fine for about 3 months, then the 'minutes' digit started failing, starting with one of the numbers only showing the top half until eventually all digits had died. Thinking it might just be a tube at the end of it's lifespan, I swapped it for the one in the seconds position, and it ran fine for another few months so I was going to get a single replacement, but then one again the one in the minutes position starting failing in the same way. That indicates to me it's a problem with the board and that particular socket, rather than the tubes. I don't want to risk killing any more tubes, so is it worth just getting a new board? Or have I just got unlucky with the used tubes and they just happened to fail in the same way? I tried testing the voltage it was outputting, and my multimeter seems to say ~194v for each pin, that seems quite a bit too high? But they all seem to be the same, so that wouldn't explain why it's only the one socket killing the tubes. Does anyone have any ideas what to do, or if a new board is the only option, any recommendations for a good reliable and ideally cheap one, available in the UK? Please let me know if you need any more info. Many thanks -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
