The simple mosfet amplifier. But little different than any other audios. I am quiet interested this project very much. because it is a class A amplifier project. the sound quality of this circuit will make you amazing. It is just a single mosfet class a amplifier circuit.
But its performance is very nice. actually a class A amplifier category are very popular with its sound quality. The listening pleasure will automatically decides you to make this single ended amplifier. approximately the power output of this circuit is very low as 5Watt.
Circuit Diagram
As a single mosfet amplifier it is very successful project. The sound quality of this circuit is not to compromise. if you are very interested in audio amplifier and sounds, you must try to listen the sound of this tiny class a amplifier. With few components and less cost is the another advantage of this audio amplifier. i will guide you to build this single-ended FET amplifier.
This is a zero negative feedback amplifier. which implies building a zero component amplifier system. The single-ended class A amplifier can be easily build with few components. To build this one you needs a Mosfet of 2sk1058 N channel hitachi mosfet and few capacitors and resistors. The power supply of 24v will be properly filtering with large valued capacitor of 4700u/60v ( power supply not mentioned in circuit ). To managing the load we are using four wire wound resistor of 10W.
