And the way vacuum tubes served most Americans for many years was inside their radios. The radio back then was frequently like a piece of furniture, in the center of the room, and filled with ...

For most of us, vacuum tubes haven’t appeared in any of our schematics or BOMs in — well, ever. Once mass-manufacturing made reliable transistors cheap enough for hobbyists, vacuum tube… ...

Why you should ditch your Bluetooth speaker for the smooth, sweet and surprisingly affordable sound of a vacuum-tube amplifier.

We have occasionally featured vacuum tube computers here at Hackaday and we’ve brought you many single board computers, but until now it’s probable we haven’t brought you a machin… ...

The transistor revolutionized the world and made the abundant computing we now rely on a possibility, but before the transistor, there was the vacuum tube. Large, hot, power hungry, and prone to ...

Which is why NASA's Ames Research Center is going back to the future with its new vacuum transistor -- a nanometer-scale vacuum tube that, in early testing, has reached speeds of up to 460GHz.

We’re struggling to meet Moore’s Law because we can’t make transistors small enough; there just aren’t the capabilities available to laser-etch them much smaller than they are right now ...

Listening to music in a vacuum--or why some audiophiles love the sound of tube amplifiers The Audiophiliac checks out the magical sound of flea powered vacuum tube amplifiers.

January 22, 2023 ‘It Sounds Human’: Audiophiles Are Embracing the Lush Sounds of Old-School Tube Amps Once nearly obsolete, the classic devices still can’t be beat for their natural sound.

1904: British engineer John Ambrose Fleming invents and patents the thermionic valve, the first vacuum tube. With this advance, the age of modern wireless electronics is born. The principle of ...
