Vacuum Tubes Valves Westinghouse WW2 Electronics at Work 

Very cool. Charming in its retro style and brilliant in its detailed explanation. Explains why that generation coming out of the war were able to transform the technology of the world and land a man on the moon.

I just found an old Westinghouse V.T. 98 radar triode under the house. My research has led me here. It has also informed me that it is radioactive 😳☢️
