GNP-7 or GNP-7As then? If so I could sort a spare. Nixies often have trouble lighting up on their standard voltages the first time they are used after a long time unlit... whacking up the voltage briefly can help...
Which drivers? 7441/74141/DM5xxx/etc. or 8xxx series etc. ? Have spares for those too...
Its very unusual for the tube itself to go - they have a very long MTBF.
Anyway, for a turns counter it really doesn't matter too much
