Re: [neonixie-l] Re: Stuck with a stuck dekatron

Hi Paolo, There are two envelope sizes for the 6167/439A. I have not analyzed whether they are date-related or otherwise different. There are also some tubes clearly Kr-85 marked, as you mentioned. I don't recall what readings I had on my Geiger counter back when I tested them, but other

Re: [neonixie-l] Magic Eye Resources

I can't offer any circuits, but one piece of advice: In the round eye tubes, the phosphor gets darker with use. They start off a light ash grey. If you are offered tubes with charcoal grey phosphors, run away! On Friday, February 5, 2021 at 3:22:13 AM UTC-5 newxito wrote: > German Elektor
