I enjoyed the refresher on how stuff works. I appreciate the time you put into it, and the carefully noted corrections to your narration. When I worked in Silicon Valley I made many field trips to the great surplus / junk stores that dot Santa Clara and Sunnyvale. Now I'm much closer to Disneyland, but when I wanted some disposable weighing boats the only answer was "the internet".
That was great! Thanks! Always wondered about the internals of a crt. You make it seem simple.
