Hey all I found some time to make a schematic. It only shows the two 74141, nixie tubes and anode drivers. I also tried blanking nixies via 74141. I would have never guessed that you meant on hex code, as I am doing this on an arduino :) Blanking nixies with 74141's give me a lot of leaking (or at least I think thats leaking), so I'm not so sure about using this method. But I do think that it's maybe possible to divide the leaking to the rest of the nixies by adding a resistor for each anode, instead of sharing them. See for yourself in the links.

But what should I do with the blanking? To be honest, I would leave the setup as is, because it seems to work fine. But if you guys think I can do something better to get a longer tube life, I will make changes to the schematic immediately. Thanks!
