D882 Audio Amplifier Circuit Diagram. Amplifier will give sound loudly than mobile phone. Hi today in this video i have shown how to make a simple audio amplifier.

To play song connect battery to the battery clipper and plug in aux cable to mobile phone and play songs. A part from the above applications it will also perform when used to amplify audio signals and it can be used in small audio amplifiers output stage of receiver circuits bell circuits audio related circuits etc. For example it can be used in power supply circuits voltage regulator circuits battery charger circuits driving motors switching any load under 3a etc.

How to make easy mini amplifier by transistor d882 using power usb 5v.

Amplifier will give sound loudly than mobile phone. Thank you for watching my video. Following image has a circuit diagram of the above project. I used here one d718 power transistor in power stage and one d882 transistor in pre amp.
