Martin,
Do have a link to that document. Are they driving the nixies directly, or
thru transistor buffers ?
Here's a little more complicated selector circuit, I made:

And here's a video
Nice circuit! I really like it and I will certainly save it for the future!
I was planning on using high voltage opto-couplers like MOC8204 or HSR412
instead of the white LEDs you are using to drive a Nixie.
With the original circuit in the datasheet they usually only use the
outputs for
David Blevins let me borrow his A108. He loaned it to me months ago, and I
finally got around to playing with it. It ends up being a very forgiving
tube. I've gotten it to work, with a supply voltage as low as 250V. It may
even go lower. I started my tests using a 450V supply. That means it
Hmm, so it would be easier to use a usual 10-counting dekatron as a
5-counter by circuit design ??
Don't know, until I fire one up. Its possible that it could be stepped
just like a EZ10B, but I'm not sure of the proper bias and pulse
levels.
From what I've read, its count direction is due to
Don't know, until I fire one up.
Can't fire one up, if I can't get one. None on eBay, nor the Russian
tube stores I'm aware of. Jan Walter don't have them either. Anyone
got one to sell, or trade ? Contact me at my personal email, if you
do.
Thanx

In case you make adapters for different dekatrons to the octal socket and
eventually make R7 and R10 switchable for higher supply voltages, you can
make a dekatron tester with the print. Don't forget to adapt the diodes D1-3
and capacitors C2-4 to the higher voltages. Some suggestions Mike
