Hello, I am a competent electronics hobbyist, but entirely new to tubes and Nixies.
I have acquired some Burroughs B6844A tubes, but I'm having trouble getting them to light properly. Using the voltages and anode resistor combinations recommended in the Burroughs datasheet (170V/15K, 250V/47K, 300V/75K), some digits light consistently, some vary between lighting and just having the lead-in wire glow, and some only have the lead-in wire glowing. Increasing the voltage seems to increase the chance of a particular digit striking in favour of the wire, but I cannot get all digits to light. I have not tried combinations of resistor/voltage apart from those suggested by Burroughs in case I make things worse. Are my tubes dead, or is there a hope for them? I don't think cathode poisoning is an issue, as when the digits do light, they light brightly and evenly.
