Television sets were a major use of vacuum tubes from the late 1940s till the mid 1970s. They are quite tricky to build, but I've found several old ones to play with, over the years.
Old tube based test equipment is also interesting, I even made a sort of functional clock using an old counter. https://www.youtube.com/watch?v=VM9TW6GcCQE I have an tube based Tek scope from the early 60s that I can use to keep my shop warm, since it dissipates about 500 watts just sitting there! Short wave radio also used tubes, I have a BC-348/Q radio receiver in my office, so I can tune in WWV.
