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 ...

For most electrical engineers, the vacuum tube or, more formally, the vacuum electron device (VED), is a quaint curiosity and artifact of the past, and with good reason: The world of solid-state ...

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 ...

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 ...

CES 2024 is just around the corner and tech companies are already providing sneak peeks of what we can expect to see on the ground in Las Vegas. LG is bringing a range of wonderful, weird gadgets to ...

In 2021 all our electronics are solid state, in that they exclusively use semiconductor devices as their active components. Some of us may experiment with vacuum tubes, but only for curiosity or ...

It has often been said that in our never-ending quest to make things better or easier through technology, we are collectively losing some parts of our souls. One area where that certainly has been ...

SōLIS, an audio brand that has been around for four decades, is constantly evolving. Many of its current offerings pair with Google Home and Chromecast devices and it made a nice showing at CES with ...
