This full-page advertisement by CBS Tubes caught my eye because of the vast array of vacuum tube shapes and sizes. It appeared in a 1958 issue of Radio & TV News magazine. Most people, even back in the era of tube-based electronic equipment, think of the standard 12AX7 type rounded top, cylindrical glass package with a plastic or phenolic base and some metal pins sticking out of the bottom. Television and radio sets were full of them, and those are what you or your parents or grandparents would yank from the chassis and take to the local drug store or electronics shop to plug into the big tube tester that was commonplace back then. However, as this photo shows there was a great variety of special glass and inner electrode configurations. If you have ever attended the MTTS (IMS) show, you might have seen the equipment display provided by the National Electronics Museum. It has an amazing collection of tube types. I was going to post a photo of a lamp I made out of a thyratron tube that was used in the AN/MPN-14 airport surveillance radar I worked on in the USAF, but alas, I cannot find it. I can't even remember at this point what happened to it - probably broke in one of our many household moves.
