The circuit consists of preamplifier, tone controls, and regulated DC power supply, while providing a power output of 18 Watts for 8 Ohm load and 30 Watts for 4 Ohms load. BC550 – an NPN general ...

As readers will know, there are already several power amplifier projects, two using IC power amps (aka power opamps). Both have been popular, and this project is not designed to replace either of them ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

If you’re building a hi-fi system, amplification is a necessary cog in the chain. While your source (turntable, streamer etc) plays your music and your speakers output it, the middle-man amplifier ...
