I'm not a fan of multiplexing nixies because of the additional current that can lead to shorter lifespan. Me neither as I can hear the whine of the vibrating segments in my old B-7971 clock I built in 1979 that is multiplexed. As for shortened life, I do not know what other manufacturers did but the Rodan GR-111pa tubes I have were designed to be multiplexed. The "a" variant were for multiplexed use and the non-"a" direct drive from what I understand from the spec sheet. The board I pulled my GR-111pa's from was definitely designed for multiplex operation as all the tube segments were wired in parallel with the anodes separate. They do work fine as direct drive tubes. I assume they have a more robust design to stand up to the demands of multiplexing. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
