I have a handful of vacuum tubes I pulled from an old black and white TV I was given, years ago. I know they work, but have not found any use for them. Most of them are pentodes or diodes, I think a couple are triodes.
Due to them not being of any use at the time being, I have always wanted to display them somehow. Any ideas on a display case design? There are 17 tubes total, two of them are large, a couple are "medium sized", and the rest are the pentodes which are the smaller bunch.
