Hello guys, in this post I make a 500 Watts mono amplifier. This is a class AB mono amplifier. Which can deliver up to 500 Watts RMS output at 8Ω ±70V, Test frequency 1khz. And 750 Watts RMS output at 4Ω ±60V, Test frequency 1khz. For this amplifier I used 5 pair of 2SC5200 and 2SA1943 Transistor.
PCB From PCBWay
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.
After 7 days I have received my PCB. You can see the PCB quality, it's awesome. I have ordered Red 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.
How To Test 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:- Biasing = 0.5-0.7V. 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 45-0-45V to 55-0-55V 6A-8A Transformer. And in Bridge rectifier, You can use 25A-35A bridge rectifier (GBU2510, GBU3510, KBPC3510) and 2 pcs. of 10000uF capacitor.
