The Single NPN Transistor Audio Preamp - HACK A WEEK
http://hackaweek.com/hacks/the-single-npn-transistor-audio-preamp/
The Single NPN Transistor Audio Preamp. Here’s a great little project that goes well with the LM386 audio amp. It’s a good first time transistor project because it’s simple and demonstrates the common emitter class A amplifier circuit with only six components in the signal path. A “Class A Amplifier” operation is one where the ...

A fully functional LM386 audio amplifier will reside inside the ribcage with eight hearing aid batteries in the spine for power. The head holds the speaker, input jack and volume control. Moving one of the arms in a raised or lowered position will turn the circuit on or off. I’ve started this project by drawing out a sketch.
Class AB Audio Amplifier - HACK A WEEK
http://hackaweek.com/hacks/class-ab-audio-amplifier/
Class AB Audio Amplifier. This week we’ll take a look at another type of audio amplifier, the class AB amp. As we saw in Hack #19 the class A amp has a transistor that is biased with a voltage that makes it essentially stay turned on all the time. This single transistor handles the entire waveform both positive and negative.

The LM386 is a type of operational amplifier (Op-Amp). Operational amplifiers have a basic task. They take an input potential (voltage) and produce an output potential that’s tens, hundreds, or thousands of times the magnitude of the input potential.

The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package. The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts.
