, and you have 170volts output, then the tube is
bad. There is no harm trying other tubes to see.

Hi Pierre
You may need to check that the enable pin on your HV power supply is set to
the correct level (depends on the model).

Hi Richard, many thx for your reply.
I assume if there is no result, the Nixie is burnt, right?

You only need a single 10k resistor in that circuit.
In your picture, remove the one at the top with the yellow wires, you would
be connecting the desired cathode directly to ground.
Additionally, you have the tube connected back to front.
The circuit you need is as follows:

Hi Pierre, did you see any light at all from the tube? You may be
OK.see Paolo's astute observation from his email.
Do you have a multimeter? Have you checked that you have 170V DC (or
thereabouts) coming from the little power supply?
Note, that the IN-1 tubes have a notoriously short
Hi Nick,
Thank you for your quick reply.
Is that mean I destroyed the cathodes while testing the tubes?

Not only you need the 10k resistor, but you need to ground a cathode. In
ASCII drawing:
+HV - 10k -[Anode || Desired Cathode] GND
In your picture it looks reversed, whch is good since you didn't put the
resistor.

Welcome aboard!
