These lightweight 1x12s boast onboard EQs and 50 or 100 watts of power – and they could be your modeler's new best friend ...

As a service to our readers, we're providing the LTspice files used in Dr. Dyer's article on simulation of the 12AX7 and the K2-W vacuum-tube op amp. 1. The model for the K2-W is established as a ...

Abstract: We present the experimental demonstration of a traveling-wave tube (TWT) power amplifier operating in the W-band (75-110 GHz) frequency range. The device is based on a serpentine waveguide ...

Hakeem Jeffries says Obamacare subsidy extension 'will pass with a bipartisan majority' Winter weather warning as 40 inches of snow to hit—travel "impossible" Scientists discover a lemon-shaped planet ...

The three-channel 50W monster is a super lightweight combo that is easy on your back while showing no quarter with its high-gain tone, and EVH Gear says its faithful to the original tube amp When you ...

Abstract: A watt-level traveling wave tube (TWT) amplifier operating above 0.3 THz has been demonstrated. This TWT based on the folded waveguide (FWG) slow-wave structure has achieved over 3.1 W of ...

Dynaco hasn’t made equipment in decades. Yet it’s still a name most audiophiles know off-hand. That’s because the American manufacturer left an indelible legacy on the world of hi-fi, thanks in large ...

Although amp modelers have radically advanced over the past few years thanks to some cutting edge tech, there are still those who believe digital guitar gear will never truly compete with the tones of ...

Part 5 provides spec summary of the GP/R K2-W vacuum-tube op amp and discusses measurement constraints/conditions and LTspice modeled output. The K2-W vacuum-tube op ...

A conventional tube amplifier has a circuit whose fundamentals were well in place around a hundred years ago, so there are few surprises to be found in building one today. Nevertheless, building one ...

The hardware is chunky and the software is clunky, but this is the best portable audio player I’ve ever heard. If you buy something from a Verge link, Vox Media may earn a commission. See our ethics ...
