Peer inside an antique radio and you’ll find what look like small light bulbs. They’re actually vacuum tubes — the predecessors of the silicon transistor. Vacuum tubes went the way of the dinosaurs in ...

Most people associate vacuum tubes with a time when a single computer took up several rooms and "debugging" meant removing the insects stuck in the valves, but this technology may be in for a ...

One of the topics we've covered multiple times at ExtremeTech is the difficulty of continuing to scale semiconductor technology, and the related problem of improving chip performance without ...

Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified ...

A vacuum tube, known as the first electronic device, is used to switch, amplify, or commutate electric signals. In the past, vacuum tubes functioned as a main part of a diverse range of electronic ...

Researchers from UC San Diego are using vacuum tube technology to develop more efficient computer processors. The research could result in faster microelectronic devices and better solar panels. Their ...
