Lets Build This Amplifier
Hello guys, in this post I make dual bridge stereo amplifier, which can deliver up to 38 watt output per channel at 4Ω. For this amplifier I use TDA7379 IC but you can use TDA7377 IC instead of Tda7379 IC. But if you use TDA7377 IC, you get 35 watt output per channel at 4Ω. This IC mostly use for high-end tv and hi-fi amplifiers. This is a class AB amplifier and have in-built output short circuit protection which is perfectly tuned for home use. 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 hour. 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. PCBWay will deliver your PCB within 7-10 days.
After 7 days I have received my PCB. You can see the PCB quality, it's awesome. I have ordered Green color PCB. But you can choose your PCB color. PCBWay provide total 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 first time at PCBWay, then you get a $5 discount coupon. So upload your Gerber today and get best quality PCB.
Testing Method After Complete This Amplifier
Check Voltages:- Check Audio Output and Audio Input voltage. Here you get no voltages 0.00V. If you get same voltages, then connect preamplifier to input and connect speaker to output.
Power Supply:- For get best performance of this amplifier, you use 12V 5A-6A SMPS or 12V Battery. (Don't increase voltage).
