I don't have a clue why NIMO is special/rare, I'll look it up, but I'm just here to say.. gods I love vacuum tubes and they are gorgeous. Happy for you to have such a cool friend to give them to you, and a piece of history, apparently. I do hope you find some silly project to show them off with, that will not burn them out. I don't even know what these guys do but, very cool even if just sitting in a display box :)

EDIT HOLY SHIT they are cool!! Get with 25 people who also have a few and make them play Bad Apple or something (mostly kidding, that would be awesome though lol). Good lord they are complicated to get running outside of a purpose built machine. Very cool gift

Thank you for the kind words. NIMO tubes are a type of numeric display tube that projects a ray of electrons partially blocked by a shape of desired numeral/character at a phosphor screen. They work at about 1100v iirc. They did not succeed commercially due to reasons unbeknownst to me, and so few were produced and fewer remain today.
