[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 ...

Rufus Turner published plans for a crystal radio with a three-transistor audio amplifier back in 1950. Germanium transistors still find use in certain applications where their low forward voltage ...

Here comes a new compact power amplifier that isn’t made in China: Pro-Ject Audio Systems’ Amp Box RS2 is made in Europe; it ...

Abstract: A class B audio-frequency transistor power amplifier is described in which the advantages of zero-bias operation and electronic overload protection are achieved through the use of transistor ...

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 ...

Abstract: The design of tetrode transistor amplifiers encounters problems of the type that occurs with other transistor uses. Desired frequency characteristics, limitations of parasitic elements, and ...

This balanced amplifier delivers the rich warmth characteristic of tube amplification alongside the accuracy of a transistor circuit, resulting in a powerful audio experience filled with intricate ...

The SERENADE Wireless amp circuit is based on a Class A design, supplemented by a precisely matched, discrete transistor amplifier circuit ... and a pair of RCA single-ended audio inputs on the rear ...

This repository has reverse-engineered schematics for the AMP-MGB (IR3R53) audio amplifier chip used in the Game Boy ... and an output stage. Power transistors Q126 and Q125 implement a class B ...
