What an interesting thing – a new take on thermionic valves for the audio obsessed, base on vacuum fluorescent display technology. According to RS Components, which is stocking the Korg Nutube 6P1 ...

[Nick Poole] shared his circuitous journey into the obscure world of homemade vacuum tubes on the Supercon 2022 stage. It began innocently enough when he saw [Usagi Electric]’s single bit computer ...

When a metal is heated to a sufficiently high temperature, electrons can be ejected out from the surface in a process known as the thermionic emission, a process that is similar to the evaporation of ...

THE precise nature of the electronic oscillations produced by thermionic valves is still, fifteen years after their discovery in the three-electrode valve by Barkhausen and Kurz, imperfectly ...

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 ...

THE control of energy at distances of thousands of miles without any other medium than the aether has been made possible by the evolution of the thermionic valve. This remarkable invention can be ...

Perhaps the only contact many of us have with the sort of valves you get in electronics these days is if we have an ageing cathode-ray tube TV, or if we know a particularly boring audiophile who is ...
