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 ...

Millimeter wave vacuum tubes, including ones like the traveling wave tube (TWT) depicted here, amplify signals by exchanging kinetic energy in the electron beam (shown as a blue line) with ...

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, ...

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 ...

Abstract: Vacuum tube electronics are analyzed when the time of flight of the electrons is taken into account. The analysis starts with a known current, which in general consists of direct-current ...

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 ...

The circuit was designed to create a power amplifier circuit that will utilize E80CC and EL34 vacuum tubes for better results while providing 35 Watts of power. E80CC – a special quality double triode ...

Vincent SA-T1 Stereo hybrid vacuum tube preamp $1,495.00 When Vincent set out to design the SA-T1 hybrid tube preamplifier they took their time, painstakingly researching every detail until each stage ...

Dr Bob has sent in the photo of the mini vacuum tube he mentioned in a comment on last month’s post ‘Intel’s Ultrabook: Re-Invention Or Red Herring?’ which compared Intel’s vaunted re-invention of the ...
