    1000W Mosfet Amplifier Circuit Mosfet IRFP240 IRFP9240

    1000 watts power quality have a design output stage 6 irfp9240 (P-Channel) and 6 irfp240 (N-Channel) used the audio input section of the lf411 JFET input a quality op-amp opamp onset 15volt zener are provided with amp circuit supply voltage + -40volt and + – 90olt two feed

    Quiescent current BD140 BD139 transistors oval connected to the ends 5k potentiometer is done with an estimated half of the audio input while there was no draw current 300mA vicinity should be adjusting accordingly can, of course, the exact value is not by trial and error you will find yourself
