About :

With the help of 2 MOSFETs, we can make a stereo amplifier. This circuit does not need a lot of voltage and the current of about 300 milliamps can easily start the circuit. By using a mobile phone charger and slightly increasing the voltage of the charger, we can start the circuit. How to increase the voltage of switching circuits is available in previous videos. 1) Use heat sink for MOSFETs. 2) It is not necessary to have a diode, but it is better to be sure. 3) Use shield or coaxial wire to have less noise. 4) The resistor on the gate and drain pin is required to turn on the MOSFET. 5) The ground or negative wire of the mobile phone output is connected to the negative of the speakers. ----------------------------------------------------- - With the help of 2 MOSFETs, we can make a stereo amplifier.
