Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

In order to achieve useful amplification from a transistor, the transistor is generally biased in the forward-active region (FAR). The FAR is the region of operation of the transistor where ...

The circuit below shows a 4-transistor utility amplifier suitable for a variety of projects including receivers, intercoms, microphones, telephone pick-up coils, and general audio monitoring. The ...

It may not be to everyone's taste, but this brand new monobloc amplifier from McIntosh cleverly blends both vacuum tube and solid-state technology in one chassis. If you’re not a serious audiophile ...

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 ...

Forbes contributors publish independent expert analyses and insights. Technology journalist specializing in audio, computing and Apple Macs. This article is more than 2 years old. The new Quad 33/303 ...

The circuit was constructed around the functionality of a Class A amplifier to create a headphone circuit. BC308 – an epitaxial planar PNP transistor used for general purpose and low noise amplifier ...

There appears to be 16 large transisitors which were mounted to the heatsink of this amplifier. It is a Planet Audio 4 channel car audio amp. From some quick Google searching, it looks like I should ...
