I built that thing a while back. I uploaded the video, for another forum,
discussing arc discharge tubes:

OMG! That 0A5 arc discharge dekatron spinner is amazing, too!
I am ignorant as to the ways of you EE masters. But I want to make one now.
Damn you!

Oh on those. If you get a regular nixie supply; 170V. Make a divider out
off 3 22K resistors, and the two voltages are 57V and 113V, which are just
rounded off to 55V and 110V. That's assuming it was dead nuts on 170V to

Oh, yes, its a timing issue. It works fine with the guides detached. Its
just more of a curiosity. Flipping the guide pins does make it switch to
K1. I'll have to analyze my circuit timing more closely to discover the
actual mechanism details. The reset is issued at the same time as the flip.

Very nice!
I like the discrete XOR gate but its a lot of complexity when you can get a
single "tiny logic" XOR gate from Fairchild, Texas or whoever for $0.10 -
one SOT-23 (as opposed to 4 diodes, 4 resistors and a transistor) and
you're there... :)
Yeah. I saw the odd voltage levels too!
Nice!
Could it be that you have a timing issue with the guides not being totally
"off" when you do the reset?
Or that the reset does not load the cathode enough so that the glow steps
to a lower potential, being K9? You can also check what happens if you
exchange the guides, then it should
