DIY 2000W High Power Amplifier 2SC5200 2SA1943

Power Amplifier circuit 2000W
Here I will share posts about power amplifier with high power that can generate power up to 2000Watt or 2kW. Also, before I publish a power amplifier with high power that is almost same with 1600W High Power Amplifier. The same power amplifier using the final transistor with 2SC5200 and 2SA1943 is good enough and powerful to drive 2 pieces of 18-inch 8 Ohm speakers. The difference is quite clear on the speaker protector, for power 2000W is not equipped with a speaker protector you can add it yourself to this circuit Audio Speaker Protector using IC555. And for the power supply is also wider ranging from 45Volt to 75Volt DC Symmetrical. This power amplifier is stereo 1000W x 2 but its bridge tie load (BTL) so the output power have 2000W RMS.

Below the schematic of 2000W power amplifier circuit:
