500W Power Amplifier with 2SC2922, 2SA1216

This 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 recomended to be place on the good heatsink. Because, the transistor will be hot. Transistor Ouput using SANKEN 2SC2922 and 2SA1216. Below describe the Circuit Diagram of 500W Power Amplifier :

Could you repeat that? can occur made to add to offered audio power amplifier? The answer is either decrease load impedance otherwise increase supply voltage. The drop the impedance, the extra current is wanted, making the construction of low impedance output stages other testing (at hand are selected other matter-of-fact limits), so consent to's increase supply voltage.
