Dear Lazyweb, I have some Nixie tubes that are suffering from cathode poisoning. I understand in principle what you can do about that, but I would rather not build it myself. Is there someone who will sell me a jig to properly "cook" these? The tubes are ИН-18 9105. Or should I just say the hell with it and buy new tubes? It seems a shame to toss them instead of repairing them, though.

Previously, previously, previously, previously, previously.
