Uni Watch: Football And Vacuum Tubes

This morning, I’m the Uni Watch guest author with an article about football and vacuum tubes. The story covers the bad old days when televisions had vacuum tubes that burned out without warning and how that affected the ability to watch a game. The story illustrations come from a brochure with the 1971-72 NFL schedule and instructions on diagnosing which vacuum tube needed replacement.

I hope you enjoy it.

I’ll repost the article on Football Archaeology in a few days.
