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 ...

Vacuum tubes disappeared from electronic products years ago. Yet there have been some lingering vacuum tube-based products in production. Vacuum tubes disappeared from electronic products years ago.

While most VEDs in common use today (traveling wave tubes (TWTs), klystrons, crossed-field amplifiers, magnetrons, gyrotrons and others) were invented in the first half of the 20th century, ongoing, ...

The venerable vacuum tube is due to take retirement. Though solid-state electronics overtook the venerable vacuum tube more than 60 years ago, more than 200,000 Department of Defense devices use ...

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 ...

1904: British engineer John Ambrose Fleming invents and patents the thermionic valve, the first vacuum tube. With this advance, the age of modern wireless electronics is born. Although the Supreme ...

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 ...

For most of us, electronic technology comes in the form of solid state devices. Transistors, integrated circuits, microcontrollers. But for the first sixty years or so of the field existing, these ...

It all began with a cheap Chinese rotary vane vacuum pump and a desire to learn the witchcraft of DIY vacuum tubes. It ended with a string of successes – a working vacuum chamber, light bulbs, glow ...

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 ...
