Todd Sharp is surrounded by a mountain of guitar amps. But he’s quick to say some of them are better than others. “That’s kind of my motto here: Life is too short to play shitty amps,” he said with a ...

LONDON — Ideas of how to exploit miniaturized vacuum tubes have emerged regularly and without much success, since the glass-envelope valve was replaced for most applications by the transistor. However ...

Although we do often see projects that take antiques and replace some or all of their components with modern equipment, we can also sympathize with the view that (when possible and practical) certain ...

While most VEDs in common use today (traveling wave tubes (TWTs), klystrons, crossed-field amplifiers, magnetrons, gyrotrons and others) were invented in the first half of the 20th century, ongoing, ...

UK-based solar tech developer Naked Energy’s rooftop solar vacuum tubes, which produce both electricity and heat, will soon be sold in the United States. Peoria, Illinois-headquartered ELM Companies, ...

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 ...

Scientists in a lab in China have developed a remarkable vacuum tube that could help make a game-changer electronic warfare device, according to a report. They developed a miniaturized traveling-wave ...

Vacuum tube amplifiers just won’t go away. I am speaking more of audio vacuum tube amps than I am of microwave amps like magnetrons, klystrons, TWTs and the like. Most other audio gear is solid state ...
