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 ...

Audio’s TH1 wireless headphones use of a genuine triode vacuum tube in the preamplifier stage, making them unique and ...

Vacuum tubes disappeared from electronic products years ago. Yet there have been some lingering vacuum tube-based products in production. Vacuum tubes disappeared from electronic products years ago.

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, ...

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 ...

In today's world, vacuum tubes or radio valves seem as dead as high button shoes and buggy whips, but DARPA sees them as very much the technology of the future. As part of a new program, the agency is ...

The circuit was designed to create a power amplifier circuit that will utilize E80CC and EL34 vacuum tubes for better results while providing 35 Watts of power. E80CC – a special quality double triode ...

Talking about vacuum tubes—or “vacuum electron devices” (VEDs), as their proponents prefer to call them—may seem like you are discussing ancient history. After all, who even considers VEDs when ...

The notion of vacuum electronics may sound ancient in high-tech terms but a new program from the scientists at the Defense Advanced Research Projects Agency aims to transform the widely-used equipment ...

In the 21 st century, it is all too easy to take today’s powerful microcomputers for granted, and as artificial intelligence continues to make inroads, the assumption is that massive amounts of data ...
