100W Basic MOSFET amplifier

100W Basic MOSFET amplifier
This Basic MOSFET amplifier is very simple to build and low cost. Is perfect for Hi-Fi amplifiers and instrument amplifiers (guitar, keyboards ...). Output power is + / - 100 Wrms at 8 ohm load or + / - 160 Wrms below 4 ohms. The simplicity of this circuit cause distortion + / -0.1%. Bandwidth at -3 dB is from 4 Hz to 96 Khz and it is limited by C1, R1, R2 and C2. (more…)
