At this point, I should clarify the difference between the IN-9 and the
IN-13
The IN-13 takes up to 5mA for a 12cm orange glow from Neon gas, and has
three electrodes. One perforated cylinder as the anode, a central wire
cathode for the glow, and a

Thanks for the info Adam. It doesn't really explain why the current is
higher / sensitivity is lower for the IN-9. I still expect the IN9 to be
brighter as the higher current should ionize more neon. Maybe I should
measure it one day.

Michel - that's exactly what happens. IN-9 tubes are significantly brighter
than IN-13, and to my eyes much better for general use. I made this thing (

the IN-13 were bigger, used less current and were more predictable to
be an
issue, right?

Glad you liked it - was my first venture into designing my own clocks. I
haven't posted a schematic, but there isn't really much to it in hardware.
The tubes are driven by single transistor voltage-controlled current sinks
which are run by an octal DAC controlled by a PIC. The rest is just HV
