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 ...

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 new type of transistor is being developed by scientists at the NASA Ames Research Center that meshes together the best aspect of semiconductors and traditional vacuum-tube technology. This ...

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 ...

The transistor is one of the most profound innovations in all of human existence. First discovered in 1947, it has scaled like no advance in human history; we can pack billions of transistors into ...

On this 60 th anniversary of the first issue of EDN, we look back to 1956 when the vacuum tube was at its maturity and transistors were about to begin their domination. The vacuum tube features of ...

The telephone company had problems with vacuum tubes, too, and hoped to find something else to use for switching telephone calls. The idea of somehow using semiconductors (solid materials such as ...

It may not be to everyone's taste, but this brand new monobloc amplifier from McIntosh cleverly blends both vacuum tube and solid-state technology in one chassis. If you’re not a serious audiophile ...
