There are 300W, 600W, 800W, 1200w versions that have been applied by removing some parts without changing the design of the original circuit much, I prepared a PCB for the 400W version. Crown XLS

Simple 2SC5200 Transistor Amplifier 100W RMS

100W Amplifier circuit provides high power with less material. Output transistors 2 2SC5200 NPN transistors. PNP transistor is not used for output in this amp design. The operating voltage of the 100W Amplifier circuit is 2X46V DC. If you want to operate at higher voltage (max. 2X56V DC), you should use 2SC3858 or similar power

100W Power Amplifier TIP147 TIP142 Transistors (Pro and Simple version)

When I found a regular PCB drawing of a 100W amplifier circuit that I had in mind for a long time, I went into practice. Darlington (TIP147 TIP142) power transistors are used in the circuit output. Ideal for active speaker system or subwoofer, guitar amplifier, home theater systems, instrument amplifier… Clone version of 100W Amplifier

2SA1943 2SC5200 200W Amplifier Circuit

The single channel 200W version of the amplifier shared in the article 400w (2X200w) Transistor Amplifier Circuit was designed as small as possible in PCB size. The power transistors of the 200W Afi circuit do not require the classic 2SC5200 and 2SA1943 quiescent current adjustment. The amplifier can deliver 100W RMS power with a 4-OHM
