500W-2000W Power Amplifier SOCL 504

Power Amplifier SOCL 504 500W-2000W
The SOCL 504 Power Amplifier circuit is now possible again as the trend amplifier, is simple and the quality is good for indoor and outdoor sound and cheap power amplifier circuit. Well, turn your trying to listen to how the 500-Watt SOCL that in fact, the result of the development of 150 Watt OCL modified for high voltage above 40VDC.

Power Amplifier SOCL 504 500 Watt has tested with 45V DC and 80V DC voltage is still good and flat sound almost all the frequency obtained and still possible in the modification to tef to get bass thicker and an addition of the number of final transistors to increase the power of 18-inch speakers.

Three transistors are VAS deliberately bolted on the PCB board though not hot, just the model let it be different from the original version. To get the maximum output power the power amplifier circuit requires a DC voltage source with a large current so that the power supply for this power amplifier circuit should use minimal transformer 20 A can be given at least 45V DC to 80V DC.

Below the circuit diagram of power amplifier SOCL 504:

  2. hi need your help can i know the dc bias of this ocl amplifier or its just adjust till 0v at the output of the amplifier .
    secondly could you please give the dimension of the pcb cause have not seen it in your description.
    thanks ...have already all components in hands just need to make the pcb .

    1. for adjusting dc bias it on RV1, adjust the trimpot until 0v. If you cant minimum 20mV this amplifier works normally.

      The PCB Size is 82mm x 72mm. See newest video, this amplifier using for subwoofer.

  14. thank you so much for this awesome amplifier.

    what will be the output if i use 35-0-35 / 20A transformer and 6 pair of final transistor ?





    please reply fast

  19. Sir i made it and i was working awesome and after few days the mje340 is heating a lot and the 10k resistor near c4793 is heating a lot , and the driving transistor c4793 also heating a lot and a1837 is little heating but output in the speaker is good .

    But my components is heating, how i fix this issue please help me sir

  20. Hello sir i made this circuit and its working fine with 35-0-35/10A transformer

    But after using 55-0-55/20A transformer the mje340 and 1837,4793 driver transistor are heating and 10k resistor and diodes near 4793 transistor are also heating .

    Sir how i fix this heating problem with high voltage(55-0-55/20A transformer) ?

    At low voltage the circuit is working 100% fine ( using 35-0-35/10A transformer)
