Mosfetli quality output amplifier circuit 3 times the output power and the drive times used irfp9240 irfp240 and two op amp circuit is used to drive the circuit in 4558 in times of peace movements do not need to set for
Supply voltage is + - 60 volts and + - 1130 rpm position volt output is also the Source schema and pcb files: 500W-mosfet-amplifier-circuit-irfp240-irfp9240-power-anfisi.rar
CAUTION Be careful when working with high voltage capacitor circuit to make sure the connection / - connect the opposite polarity high voltage circuits large explosions could be insured before you turn the power line, use protective glasses

coolet.. thanks for the info, is that schematic correctly drawn? theres a low value resistor 3.3 ohm 1watt connected from speaker output directly to signal ground ( at the left corner of the schematic) maybe it will blow when driven at high power...thanks

can you attach the pcb layout and parts? i can't open it over here. we'll confirm it from that pcb layout.
