Since the invention of microelectronic devices like transistors and the integrated circuit in the 1940s and ’50s, semiconductors have been the backbone of electronics. However, current microelectronic ...

The project was designed using 6T9 vacuum tubes to build an amplifier device that operates in Ultra-Linear (UL) mode. The tube amplifier circuit works better in Ultra-Linear mode which used to operate ...

John Dunn recalls a close call with at at-home vacuum tube experiment and shudders at the thought of using another particular ...

Remember those old-timey room-sized vacuum-tube-powered computers with less processing power than your smartphone? That tech might be making a comeback, thanks to work from scientists from UC San ...

EASTHAMPTON — In a world ruled by the microchip, David Mell’s customers at Viva Tubes crave the soft electric hum and warm audio tone of the old-fashioned analog vacuum tube. Tubes — simple devices ...

The triode vacuum tube might be nearly obsolete today, but it was a technology critical to making radio practical over 100 years ago. [Kathy] has put together a video that tells the story and explains ...

For most of us, electronic technology comes in the form of solid state devices. Transistors, integrated circuits, microcontrollers. But for the first sixty years or so of the field existing, these ...

Call me old fashioned but when I see the comforting glow of a vacuum tube I know that I'm in for some sonic pleasure. And that's precisely the thinking behind the aim AS301DTS USB audio tube headphone ...
