[Paulo] just tipped us about an Excel based high frequency transistor amplifier ... familiar with these class A amplifiers, commonly used to amplify small audio signals. Skipping over the fact ...

The British high-end hi-fi brand is reviving the design 57 years after it first made transistor-based amplifiers respectable. Teased in prototype form at May’s High End audio show in Munich ...

The HiFiMAN SERENADE Wireless DAC/Headphone Amplifier offers lossless streaming over Wi-Fi for $200 less than its predecessor ...

The GaAs FET offers in its simplest form a device having somewhat more convenient impedances for matching than the bipolar device and it is also capable of exhibiting much superior performance above ...

Grimm Audio is known for its MU1 streamer and LS1 playback system, an all-digital playback chain. More recently they have ...

Is this £10 Chinese audio kit better than any transistor amp simply because it has a couple of tubes? We don’t think so. There’s one more moment in which you’ll hear distortion mentioned in ...

In this chapter we will study the transistor differential-amplifier circuit. This is a very important transistor circuit, as it is the basis of the operational amplifier (or op amp), one of the most ...
