I have my latest prototype of the radio controlled IN1 nixie/ IV9
bargraph/ OG3 dekatron clock working.
It syncs to the npl time signal fine, and does error checking every
minute, you can adjust the time on a single button if theres no
signal, it keeps time on its own too if required.
Heres some na
In9's were in the bits box, simple as that really, judging by the
colour its argon, I got it at 10mA full scale, I spose the accuracy
isnt all that good, rusky stock.
The tube gets warm after a while it burns around a watt or so.
Good to see that the setup for the IN1's looks ok to you guys.

May or may not be different: IN-9s come in both purple (argon) and orange
(neon).

Thats interesting, I'm using 4 by IN1's, but not a a101 I have a OG3
single pulse dekatron.
I have a supply breadboarded, it puts 210 out for the nixies, I use a
12k anode resistor, befroe you shout my tubes are multiplexed by 5 (4
tubes and another slot for some neons).
My supply uses a 555 I like

Yep, the ripple voltage increases dramatically, per multiplier stage,
given the same current draw. But the nixies are the devices that draw
the most c
