Vacuum tubes fueled a technological revolution. They made the amplification of signals a reality for transatlantic telephone cables (and transcontinental ones too), they performed logic for early ...

If you were building a tube amplifier in the early 1990s ... still use travelling wave tubes, and very high power industrial equipment that uses vacuum and gas-filled tubes for control or ...

Soundsmith, renowned for its high-fidelity audio equipment, has introduced the MOSTUBE ONE, a solid-state replacement for popular power vacuum tubes. It can replace a range of power tubes ...

The transistor was a solid (thus the term "solid-state technology") but had the electrical properties of a vacuum tube. Yet it had none of the drawbacks: it was cheap, sturdy, used little power ...

There are a couple of reasons I suspect it's taken this long to see a vacuum tube in a pair of headphones. Tubes are hungry beasts, with higher power draws than other methods of amplification. They ...
