The AmpRx Brownie can tweak your amp’s voltage for maximum tone – and it could be your key to finally unlocking Eddie Van Halen’s coveted ‘Brown Sound’
NAMM 2025: AmpRx has sought to shake things up for tube amp users by releasing the Brownie – a nifty voltage controller tool ...
You'll need a pretty amazing pair of speaker to justify this amp, but it's made for the truly hardcore, with equally hardcore ...
Current-feedback amplifiers have a higher slew rate than do voltage-feedback amplifiers. As such, current-feedback amps can better solve high-speed problems than their voltage-feedback counterparts.
The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...
NAMM 2025: AmpRx has unveiled Brownie, an voltage optimising power supply that’s designed to give your tube amp exactly what it needs to perform at its best. Now, AmpRx has made voltage attenuators ...
As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...
It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...
