Yes, the double pulse situation is the relevant one here - the other two on
the datasheet refer to specific valve circuit configurations that were used
at that time to generate the guide pulses. Modern components make the job
much easier in most ways. The datasheet recommended conditions call
I found a reference:

that explains the difference. So I am using double pulse rather than an
integrated single pulse to get the delay.
The data sheet implies I should be using -80v pulses to drive the rings. I
guess I will up the drive voltage when my
I tried another Dekatron but I'm not sure what it is, and it doesn't work.
The glow just flickers back and forth on adjacent elements.
This tube looks a bit like the GS10C/S but has no markings, has a metal
base, and the end is domed instead of flat. It fits the same socket and
appears to have

Hi,
Update on this, was able to remove the cap with only a few
So far it looks promising. I soldered the connector and the IC with the
input protection components and then connected the board to the PC. The PC
sees the device as COM port and I was able to reprogram the chip (FT_Prog
utility) so that it negotiates 500mA.

Good to hear - another successful neon spinny thing!
