This power amplifier circuit is a 1600W at 8 Ohm mono circuit that uses transistors as an amplifier. Almost same with 2800W high power amplifier circuit, For stereo power amplifier circuit, you can use this circuit 2x and will issue a power of 3200W. Let us first see the circuit schematic below.
1600W High Power Amplifier Circuit Diagram
In the buffer circuit coupled with op-amp ic 4558, supplied 15VDC voltage, circuit power supply you can see in the picture is flavored transistor D313 and B507. Driver circuit using transistor MJE340 MJE350. For use transformer, it's using one transformer by one circuit mono. CT of the transformer is not connected to the ground, will be a short-circuit. Due to this 1600W power amplifier circuit just use a plus and minus voltage only.
PCB LAYOUT for 1600W high power amplifier circuit
The Power amplifier using final transistor 2SA1943 and 2SC5200 12 Set, for more powerful output amplifier using an original transistor. You can see the PCB Layout transistor as many as 12 sets by channel (Mono Amplifier) in order to issue a power of 1600W or 1,6kW at supply voltage 65VDC.
