[Ynze] has built an audio amplifier that looks and sounds ... his local 230V mains down to +25V and -25V. The amplifier circuit itself is simple – a few discrete components surround the LM3886 ...

The opamp circuit is simple. We might have considered an LM386 or some other integrated audio amplifier block to get better performance without blowing up the parts count. Technically ...

Amplifiers and oscillators are important circuits that appear in many different configurations and perform many different functions in modern electronics. Most amplifier and oscillator circuits were ...
