Yes, I noticed that there are mainly high power / frequency types but it is interesting.
I suppose, when talking about beam tubes there are quite a few entries we could add, including the Russian rod tubes we know well. It wouldn't take a lot of doing to produce an article of more 'down to earth' in terms of more mass market / consumer / low power and size / availability /cost. The list of VHF / UHF valves would be a good start although many of them may be known but, I suspect, seldom seen.
