Mystery
Maybe one of you guys can answer this question.
The guy that lived in my home before I did was an "uber prepper". The stuff he did makes me feel completely unprepared by comparision. He had underground food storage, a greenhouse, a fallout shelter, bars on the windows, everything. One the things that I saw before I moved in has made me wonder.
One of the outbuildings was an old chicken coop. He had a small "telephone pole" about 8' high with power lines running from his home to the chicken coop. An old television aerial was beside the coop. Inside, there were cartons of old vinyl records and boxes and boxes of these little flat pieces of wood, about 1"X8"x8". Each piece of wood had wiring on it with a light bulb, a switch and an old vacuum tube. There were also some cartons of loose vacuum tubes.
Now, the guy was a veteran, a radioman in WWII. He had a radio repair shop in the garage with an oscilliscope and everything.
What was the purpose of the little blocks of wood, each with a single vacuum tube?
