Circuit diagram of audio power amplifier driver + final transistors:
This audio power amplifier has a low character and has high power output, so many audio lovers choose this type of amplifier because the bass boom is very pronounced. To make this audio amplifier so powerful need a power supply which is sufficient to let the results that can at maximum transformer minimum 20A 45-75v output and the good quality of components.
