Hello experts, I recently bought a set of IN-9 tubes for a diy audio spectrum analyzer.
Here are links to the pictures of one of the tube: http://www.flickr.com/photos/svkr2k/8550925083/in/photostream http://www.flickr.com/photos/svkr2k/8550925431/in/photostream/ http://www.flickr.com/photos/svkr2k/8550925643/in/photostream/ Is this really new one? I noticed that the backside of the tube has black deposits like it was used? Any ideas? I'm totally new to nixie tubes. -rkvs. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
