Taoglas, a provider of antennas and internet of things components, has expanded its TFM series of multi-band global ...

Like Folkvangr, the Schiit Valhalla 3 operates as a OTL/OCL design—no output transformers, no capacitors in the signal path. Translation: your headphones are getting raw tube power straight from the ...

We want to have a two-pole, 15-amp breaker to power this -- one on each leg. And that's perfect. You have that open spot. If you didn't, you'd have to share with another circuit or take something ...

Most wolves are packed into the northeast or southeast corners of the state. Wolves made gains in the North Cascade Range, but no wolves were found farther west than Chelan County in north-central ...

There’s a mystique among both audiophiles and musicians about vacuum technology, thus having a tube amp still carries a ... it’s not for audiophiles. The circuit is a pretty conventional ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter ...

This Pre-Amplifier circuit is a minimalistic design, a.o. inspired by valve design, which should help sound clarity. With 5 transistors, it has 0.1% distortion (expected from 60dB loop gain) up to ...

Abstract: The development of practical useful power in the uhf band was made possible through the use of the high-powered cascade klystron amplifier. This amplifier is discussed here together with the ...

However, silicon may make a comeback in this application area as the substrate for a GaN-based amplifier, known as GaN-on-Si ... epitaxial deposition of GaN on a silicon wafer, followed by circuit ...
