Mesa/Boogie is set to continue its current form of reviving cult classic tube amps with the announcement it will be bringing back the hallowed Dual Rectifier. Set to drop January 14, the upcoming tube ...

Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

This lab seeks to illustrate the fundamental operation of uncontrolled rectifier circuits. The waveforms associated with these circuits are visualized using simulation and experimentation. The circuit ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

Superbly built with a wide range of classic to metal tones and oodles of volume: add Vonhatski to your must-try list. In this era of austerity, it's a rare and auspicious occasion to be able to ...

Ronald James Rockwell, right, and Clyde Haehnle. The occasion was Rockwell’s 1965 retirement party. You don’t hear a lot about homebrewing radio gear these days; it’s just too easy to call a ...

API Technologies Corp.’s Rugged Mobile Rectifier is a portable commercial off-the-shelf (COTS) multi-application solution designed for powering C4ISR command and control communications systems and ...
