Hello Friends, In this post I make a 200W Stereo amplifier using TDA7294 IC, which can deliver up to 90W RMS output per channel at 4Ω ±35V. This is a flat frequency amplifier. So for that, all frequencies are very clear. You can hear all frequencies very clearly. 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 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.
PCBWay, a prominent manufacturer of printed circuit boards (PCBs), is celebrating its 10th anniversary in 2024. Over the past decade, the company has become a trusted name in the electronics industry, known for its high-quality PCB production and manufacturing services. PCBWay offers a variety of services including prototype PCB assembly, small-batch production, and custom PCB manufacturing, catering to hobbyists, engineers, and large-scale manufacturers. To mark this milestone, PCBWay is likely hosting special events, promotions, and possibly launching new services or innovations. Their anniversary celebrations often include contests, giveaways, and discounts, creating opportunities for customers and the community to engage and benefit from their offerings.
After one week I received my PCB. You can see the PCB quality, it's awesome. I ordered Black PCB. But you can choose your PCB color. PCBWay provides 9 color solder masks - 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. The maximum Layer is up to 14 Layers. If you order PCB for the first time at PCBWay, 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 24-0-24V 5A Transformer.
