High End power amplifier is the most circuit that searching for Qualiaty Sound and performance its power amplifier. This High End 500W power Amplifier Open Air , the meaning of open air is power amplifier very matching for outdoor sound, that the sound is open to air. So every people can listening on long range. Power amplifier using Transistor Sanken as A Final Transistor the serial is 2SC2922 and 2SA1216. Power Supply voltage need + - 50Volt DC. This circuit diagram and PCB Kit for High End 500W power Amplifier Open Air.
Circuit power on schematic diagram is mono amplifier, so if you need a stereo power amplifier you just multiple circuit to as you need. For final transistor Q5,Q6,Q7,Q8 = 2SC2922 , and Q10,Q11,Q12,Q13 = 2SA1216. Place the final transistor into alumunium plat cooler. And if you need stereo power amplifier see this diagram for component placement and wiring circuit.
