Thank you for the suggestion. But shouldn't this device, after the initial "setup" of the voltage across itself and the current flowing trough remains mostly on the same voltage drop? And since the maximum voltage drop that's specified in the datasheet is cca 4.5V, shouldn't (anode voltage - nixie tube voltage drop = 30V) this leave enough margin for the "diode" to absorb changes while allowing the tube to maintain constant voltage drop across itself?
