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 is just that: a glass tube surrounding a vacuum (an area from which all gases have been removed). What makes it interesting is that when electrical contacts are put on the ends, you can ...
Why might an engineer use a vacuum tube over a solid-state transistor? This question is especially interesting since most engineers graduating today do not have a background in vacuum tube circuit ...
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 ...
