Yep, I grew up on wires and glowy things. One of my favorite books in the school library was A Boy's First Book of Radio and Electronics by Alfred P Morgan. This was in the mid 1960s. I so wanted to build the one-tube regenerative receiver from the book, but the book was already old then and most of the parts were unavailable.
I do own a tube tester similar to the above, by a different manufacturer, though.
