1000W Class AB Driver

Lets Build This Amplifier

Hello Friends, In this post I make a Driver for 1000 Watt class AB amplifier. You can expand this amplifier up to 1000 watt using more transistors and 50-0-50V To 60-0-60V 15A To 20A Transformer. 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. 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 Red 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.

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:- Bias volt 0.5V to 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:- If you use this amplifier as 100 watt amplifier, then you use 30-0-30V 5A Transformer. And if you expand this amplifier up to 1000 watt, then you use 50-0-50V to 60-0-60V 15A to 20A Transformer.
