100w Amplifier Ckt Diagram. A power amplifier circuit design using sanyo s ic stk4221 has been explained in this article. It is basically used to improve the bass quality of audio signals.

At the beginning of the first stage amplification a filter section blocks unwanted frequency noises. The power amplifier circuit is capable of lifting 12inch speakers with 200watt 8ohm power both used for mid midbass and subwoofer. In the scheme the final transistor used tip142 tip147 for the transistor datasheet you can find at datasheet file base.

The inclusion of a neatly designed pcb layout makes the assembly rather.

The amplifier circuit diagram shows a 2 5w 2 stereo amplifier. The power amplifier circuit is capable of lifting 12inch speakers with 200watt 8ohm power both used for mid midbass and subwoofer. There is a diagram pcb drawing and a list of materials. The idea was developed a long time ago by the hitachi researchers and still it remains one of the favorite designs of all time considering the involved simplicity against quality.
