Schematic & Wiring Diagram

This is a 300W power amplifier OCL circuit that the circuit has been stout kit on the market. If you're fanatical concerning the use of transistors 2N3055 and MJ2955 jengkol then this circuit is that the answer. This power amplifier OCL circuit delivering a blasting 300 watts to a four Ohm speaker.



The amplifier circuit is very least expensive and cans be powered from twenty four to 32 V/5A twin power supply. you must do that circuit. Its operating great. because four transistors (2 x 2n3055 and mj 2955) on the final amplifier can of some very hot then add the aluminum finned cooler and also the fan so the transistor is not too high temperatures.
