500W Power Amplifier 2SC2922

This high-power amplifier boasts an output power of around 500 Watts, requiring a compatible voltage supply of under 63 Volts. It is recommended to place the transistor output on a good heatsink to prevent overheating. The amplifier uses SANKEN 2SC2922 and 2SA1216 transistors. If you wish to convert it to stereo, you can multiply it, resulting in a power output of approximately 1000 Watts. Here is the circuit diagram for the 500W Power Amplifier:

Can you say that again? Is it possible to enhance the audio power amplifier by adding more power? The solution is to either reduce the load impedance or increase the supply voltage. By lowering the impedance, we can achieve the desired extra current, which may require additional testing for the low impedance output stages (within certain practical limits). Therefore, let's opt for increasing the supply voltage.
