MOSFET based amplifiers as we all know are outstanding with their sound qualities and they can easilly beat the performance of other counterparts based on power transistors or linear ICs. However amplifiers based on mosfets are not always easy to design or make. Moreover after assembling a prototype, testing to perfection always remains an issue with new electronic hobbyists. You might have come across many hi-fi complex mosfet amplifier designs, but might have not dared making it just because of the above reasons. The simple mosfet amplifier circuit diagram is super simple to build and yet will provide you with a crystal clear 100 watts of raw music power that all the listeners will cherish for a long time. 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. Looking at the figure we can understand the circuit with the following points: The involved...
