They are probably used, the pins are shorter than on unused tubes, they are of equal length on new tubes. It also looks like the single mounting pin in the opposite end is missing, this sometimes leads to gas leaks as the glass breaks easily when that pin has been cut off.
They are similar to Polyatrons, but they have a purple shine, and driven like the A-201, but need phase driving pulses like a Burroughs self scan display, which can be seen in the datasheet pictures in the auction. They are pricy, usually goes for a tenth of that price from Russian sellers, but they are very rare! /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
