TMOS75Wx2 power amplifier circuit

It is a 75W×2 dual-channel power amplifier circuit composed of T MOS 150. The input pre-stage of the circuit uses
TL084. Its input terminal is a low-pass filter composed of a T-shaped network . 1/4TL084 and RC network form an attenuation
feedback tone control circuit oTL084. The output of the 532 0 circuit can also be used to control the circuit. A
5.6rlt2W resistor should be connected in series between the terminal and the speaker , and in parallel with the inductor. The inductor coil can be wound with 0.8mm enameled wire on a skeleton with a diameter of
20 turns. The tone potentiometer should use a 100kfl coaxial double potentiometer.
    The capacity of the power transformer should be no less than 50w, and the rectifier component can be 1N5404. The filter capacitor should be between 6800 and
1000tiF. The power amplifier module should be equipped with a heat sink with a large enough area and ensure good contact.
