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 ...

Vacuum tube amplifiers just won’t go away. I am speaking more of audio vacuum tube amps than I am of microwave amps like magnetrons, klystrons, TWTs and the like. Most other audio gear is solid state ...

Eurekalert – Vacuum tubes have been retro for decades. They almost completely disappeared from the electronics scene when consumers exchanged their old cathode ray tube monitors for flat screen TVs.

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 ...

Nothingness might not sound very useful. In fact, the opposite is the case because nothingness – in the form of a vacuum – has played a major role in the history of electronics. Until the invention of ...

Restoring a vintage radio receiver has the potential to be a fun weekend project, but it pays to know what you’re up against. Especially in the case of vacuum tube electronics, running down gremlins ...

English engineer John Ambrose Fleming received a patent for the thermionic valve, better known as the vacuum tube, on November 16, 1904. The two-electrode vacuum-tube rectifier, which Fleming called ...

And now a page from our "Sunday Morning" Almanac: November 16th, 1904, 110 years ago today . . . the birthday of an invention heard 'round the world. For that was the day the British inventor John ...

Solid-state technology all but obliterated the vacuum tube market in the early 1960s. So why are tubes still popular with audiophiles and musicians? Ex-movie theater projectionist Steve Guttenberg has ...

The notion of vacuum electronics may sound ancient in high-tech terms but a new program from the scientists at the Defense Advanced Research Projects Agency aims to transform the widely-used equipment ...

The transistor is one of the most profound innovations in all of human existence. First discovered in 1947, it has scaled like no advance in human history; we can pack billions of transistors into ...
