Hello Friends, in this post I make a 200W mono amplifier. This is a class AB mono amplifier. Which can deliver up to 170W RMS output at 4Ω ±35V, Test frequency 1khz. And 130W RMS output at 8Ω ±40V, Test frequency 1khz. This IC is specially designed for active studio monitors, for its low noise distortion. This IC has in-built short circuit protection and over-voltage protection, So for this reason, this IC is more expensive than other IC. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to www.pcbway.com for manufacturing my PCB. PCBWay are the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil and PCB Assembly Service. 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.
You just need to upload the Gerber File, and select the quantity, color, silkscreen, thickness etc. Then select your country, and shipping method and then Pay. www.pcbway.com will deliver your PCB within 7-10 days.
After one week I received my PCB. You can see the PCB quality, it's awesome. I have ordered Yellow PCB. But you can choose your PCB color. PCBWay provides a total of 9 color solder mask - Green, Blue, Red, Purple, Black, White, Yellow, Matte Black, and Matte Green. On PCBWay you can get 100x100mm 2 Layer PCB only at $5. Maximum size PCB you can get 500x1100mm. And maximum Layer is up to 14 Layers. And If you order PCB the first time at PCBWay, then you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.

Series light test:- After complete this board don't forget to series light test. When you will on this amplifier via series light, it glow for some time (1 - 2 sec). Then series light will turned off fully. If the series light will fully turned off, then check the voltages.
Power Supply:- Use 18-0-18V to 24-0-24V, 5-8A Transformer.
