Very compact 100W amplifier.
Hello Friends, I made a 100W mono amplifier in this post using a pair of 2SC5200 & 2SA1943 Transistors. which can deliver up to 70W output at 4Ω ±45V. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to PCBWay to manufacture my PCB. PCBWay is the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil, and PCB Assembly Services. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hours. And they distribute, worldwide. The more you order, the less price you have to pay.
Very compact 100W amplifier.
