500W Power Amplifier 2SC2922, 2SA1216 with PCB Layout Design

This is high power amplifier has Output power about 500 Watt with the compatible voltage supply is under 63 Volt or same. If this amplifier operated the transistor output recommended to be placed on the good heatsink. Because, the transistor will be hot. Transistor Output using SANKEN 2SC2922 and 2SA1216. This amplifier is mono circuit if you want to stereo you can multiple it, and the power output is about 1000Watts. Below describe the Circuit Diagram of 500W Power Amplifier:

All devices are rated at 230 V, with the power transistors has a dissipation of 150 W and the drivers are 50W.This circuit describes a process amplifier, power supply and the tests that are inherently dangerous. Nothing described in this article should not even be considered unless a wealth of experience, we know exactly what you are doing and are willing to assume full responsibility for 100% of what you do. There are design issues that may require analysis, fault detection and / or modification.

    2800W High Power Amplifier Circuit [Updated!]

    Mono high power amplifier circuit is actually powerful, output about 1400 W, but if this high power amplifier circuit is doubled and you want to create stereo power amplifier, this high power amplifier circuit the necessary components and PCB requires two-fold. So if the stereo high power amplifier 2 X 1400W Power Output ( 2800W ).

    Power Amplifier Circuit Diagram is still less by looking at the circuit that was so below, the finished circuit has been added with gains, using two JRC4558 IC  the picture IC where it can be seen below. For circuit buffers, drivers, and booster use multiple transistors and other components (can be seen listed component). And high power amplifier project that is so below is just part of the buffer and driver while the booster has not been made. For additional transistors in the booster or high power amplifier, end scheme can be found Booster output power amplifier. For bass booster using this circuit:
