You have to be careful with IV-26 displays, because there are three incompatible types - one with the dots tied together to make horizontal-tube clocks, another with the dots tied together to make vertical-tube clocks, and a third where each dot is individually selectable. You're also limited to vertical mounting if you want to do horizontal scrolling or other effects. The large Elektronika 7 clocks mount either 11 or 12 tubes horizontally, but of course then you get a gap between digits due to the wiring at the tube bases. QC on the IV-26 displays was not particularly great - it's rare to find a complete dud, but in replacing all the tubes in a bunch of Elektronika 7's I've found individual dots that didn't light, a surprising amount of contaminants on the dots, and the tubes start out with bizarre brightness artifacts, then settle down after 24-48 hours, then at around 5000 hours they start developing dark stripes under the filament line, until some dots barely light at all at around 15000 hours. Part of that is that the Elektronika over-drives them, and the large Elektronika 7 doesn't have a bright/dim switch, while the smaller one does. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
