Thanks for that interesting statistical work. They are too expensive for my tastes. Problem is, if I decide to build a project with some sort of tube, I prefer to ensure that I can stock at least two full sets of replacements. So I'd need 18 tubes to commit to a clock project (I just like clocks!). That would be $900 at today's prices. If the B7971 was the only thing going I might consider it. But I have IN-18s, ZM1040s, IV-13 numitrons, cheap VFD tubes, CRTs, and piles of smaller Nixie tubes to make clocks from. Plus, I can get brand new 4-digit Vishay plasma displays, 2" high alphanumeric chars, for about $33/digit. How much did B7971s go for at the beginning of the "fad" circa 2000? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
