PCB Layout & Schematic:-

Lets Build This Amplifier

Hello Friends, In this post I make a 200 Watt mono amplifier using 2pcs. IRF540N and IRF9540N MOSFET. For driver of this amplifier I use LM393 IC. For make coil of this amplifier, must use LCR meter. Because 50% sound clarity is depended on it's coil, and 50% on circuit. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to 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 one week I have received my PCB. You can see the PCB quality, it's awesome. I have ordered White 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

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.

Check Voltages:- Check Speaker 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 30-0-30V 5A Transformer.
