Seems like it was most likely made in late 86 or 87. I'll see if there are any later date codes. The power supply is interesting, opens like a book with board on one side and power transistors/heat-sink on the other.

I found a detector on ebay. Will test it out when it gets here. I'm not sure how they are driving the tubes since I don't see the usual driver chips. I'll examine the board and see if I can figure out how they're doing it. Also I have a video of the display. Not a very good video but I'll take another when I have the detector. https://youtu.be/BSRXjYZmnD8 -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

Some of the parts have date-codes; looks like 1984 to 1986. Maybe post-Chernobyl equipment ??

Forgot to mention. The big black plastic box on the first board contains the quartz crystal tube. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

There are lots of geiger tubes for sale on eBay. If you could post a high res picture of the inside of the equipment probably some of us could help. I am a big fan of geiger tubes (hey, they have gas inside !!!) and habe bought more than a couple from the ex-USSR.
