How It’s Made – Vacuum Tubes

Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to.

    Does anyone else remember when every grocery store in the US had a vacuum tube checker machine for customers to use? The TV’s getting dark? Better pull some tubes and check them.
