I didn't finish a clock or something like that, I just made sure that I could drive them properly and then put them away for future projects. I either fed a true sine wave signal to the transformer from an oscillator or used a square wave with a transistor driving the transformer and made sure that the output was a proper sine wave without too much distortion or over tones. Even when I ran them from a dynamotor producing a perfect sine wave at 400Hz they didn't shine anywhere near as nice as in the auction photos on Ebay - my guess is that the photos the seller's show have been adjusted (manipulated) to show a much better shine than the actual displays show, they are a lot more grainy and have a lot lower intensity compared to the ones in the auction photos. I bought a few each from all seller's I could buy from and all were grainy and shone a lot less even with a setup with the dynamotor that one seller claimed he ran them from. I don't think all of the ones I got were bad or damaged but that it is their true condition. I also read (in a test I translated with Google translate) in a Russian book that these displays age over time even when they aren't used due to their construction. The small glass encased ITEL2 displays, single segment ones, seem to work a lot better, maybe due to their construction.
