Not the one with the title of this post, why crazy sound ? Because of circuit power amplfier is really crazy, sound is powerful. By having a power output of 1700W Mono at 8 Ohm load with power supply voltage of around 110VDC. This power amplifier have featured Indicator clip and speaker protector circuit. Final transistor using Sanken C3264 and A1295. Bellow the circuit schematic and PCB Layout.
Crazy Sound 1700W Power Amplifier Circuit Diagram
For the initial setup, VR-2 at the position to the left of the VR-1 at the center position. Then the VR-1 setup. Avometer position in DC volts, Avo + to the speaker avo - to ground. Up to 0 Volt. After the VR-2, from a base Sanken SC (NPN) to the base of Sanken SA (PNP). avo + to base SC and avo - to base SA, max voltage should be 1 volt.
