EASTHAMPTON — In a world ruled by the microchip, David Mell’s customers at Viva Tubes crave the soft electric hum and warm audio tone of the old-fashioned analog vacuum tube. Tubes — simple devices ...

For decades prior to the advent of the transistor, the amplification of electrical signals was achieved through the use of vacuum tubes. Invented in 1904 by British electrical engineer John Ambrose ...

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 ...

A GIF circulating on the Internet of a data cable being attached to a 1945 computer has been followed up with detailed information about the machine by a Twitter account. It explains what this ...

Linear, small-signal AC models can be useful in the analysis and design of vacuum-tube-based circuits. Under large-signal conditions, nonlinear models are typically required. Almost 120 years ago, ...

In 2021 all our electronics are solid state, in that they exclusively use semiconductor devices as their active components. Some of us may experiment with vacuum tubes, but only for curiosity or ...

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 ...

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 ...

Scientists in a lab in China have developed a remarkable vacuum tube that could help make a game-changer electronic warfare device, according to a report. They developed a miniaturized traveling-wave ...
