Vacuum tubes fueled a technological revolution. They made the amplification of signals a reality for transatlantic telephone cables (and transcontinental ones too), they performed logic for early ...

Vacuum tubeIs an electronic component that performs signal amplification, detection, rectification, etc. with an electrode enclosed in a glass or metal tube whose inside is evacuated. Until a ...

The transistor revolutionized the world and made the abundant computing we now rely on a possibility, but before the transistor, there was the vacuum tube. Large, hot, power hungry, and prone to ...

We’ve all seen electronic components that have been coaxed into releasing their small amount of Magic Smoke, which of course is what makes the thing work in the first place. But back in the old times, ...

In today's world, vacuum tubes or radio valves seem as dead as high button shoes and buggy whips, but DARPA sees them as very much the technology of the future. As part of a new program, the agency is ...

A travelling wave tube shows how far vacuum electronics has come. Mention vacuum tubes and some people (those old enough and/or historically minded) might think of ENIAC, the first electronic digital ...
