From The Auction
Here is a tv camera tube that has a fixed internal image that appears to be the complete ASCII standard character set. This tube is in original box which had that foam that turns to red goo and it has seriously corroded the base pins. The remainder of the tube is in great shape and appears to be unused. There is a final test sheet, very faded with it showing test conditions etc. I believe that special chemical treatment will recover usability of the base pins but not guaranteed. They are not bent or broken.
