Enter an old Radio Shack P-Box stereo amplifier kit. After a few modernizations and tweaks, the result is an 8-transistor stereo amplifier that’s aesthetically pleasing, sounds great ...

See as a 36-transistor, 3000W amplifier is expertly restored to its full potential. With precise repair techniques and ...

Dive into the incredible restoration of a 16-transistor amplifier as each part is carefully checked, cleaned, and restored to perfection. This project includes washing and repairing every component ...

Biasing is the process by which one sets the DC operating point of a transistor amplifier to a known and repeatable point in this forward-active region. If you do your biasing correctly, your ...

Peter Walker’s great circuit innovation for the 303 – the ‘triples’ output stage – remains at the new amplifier’s heart. A breakthrough in transistor amp design, it effectively forms a feedback ...

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 ...

As understood from Chapter 5, the bipolar junction transistor is a current amplifier of its own. However, it can be made to amplify voltage also, as will be discussed in this chapter. The key factor ...

Without a doubt, more current came out of the sandwich than went in. It was a working amplifier. The First Junction Transistor The first junction transistor had been born. But It Wasn't a Very ...
