The literature on power amplifiers frequently discusses the importance of power-supply rejection in audio amplifiers, particularly in reference to its possible effects on distortion [4]! I have (I ...

However much care is taken, it is very difficult to keep all traces of transformer-induced hum out of the signal circuitry. It is highly irritating to find that despite the cunning use of low-noise ...

Power supply design is a broad field, requiring entirely different tools and techniques depending on what you’re working with. Creating a low-cost and compact mobile phone charger is a completely ...

More often than not we see folks on our forums and other forum websites debating how powerful a particular amplifier or receiver is based upon a single test popularized by many print magazines and ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...

As audio/video hobbyists, most of us grew up thinking that if we have an amplifier with 50 watts of rated output power into 8-ohm speakers, and that combination produces reasonably clean and loud ...

The Emotiva XPA-2 is a two-channel amplifier is one of the most powerful, highest value amplifiers we've reviewed to date. It is a lone wolf in a pasture of sheepish amplifiers. Power output: 250 ...

Have an old Ampeg V4 100w tube amp. Power! Old house with shitty electrical service. Almost two-wire everywhere. If I turn on the A/C upstairs it browns things out. Same with the fridge downstairs. My ...
