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 ...

NAMM 2025 might have us all focused on what’s new but maybe the biggest story to come this month in guitar amplification will have have us in a nostalgic mode, taking us all the way back to 1992 as ...

You can combine a carefully chosen op amp, a low-threshold P-channel MOSFET, and two feedback resistors to make a rectifier circuit with less forward drop than a diode (Figure 1). The rectified output ...

Plug into one and you'll find it very hard not to be impressed - the updated Dual Rectifier is set to be amp of the decade… again! One of the top five rock heads in the world. Killer tone. Huge ...

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 ...
