Welcome back to another interesting audio amplifier project. Today’s I’m going to share about the useful and trending audio amplifier circuit and it’s free PCB layout for free. This amplifier is provided the RMS power of 200 to 300 watts per channel.
Nowadays this circuit and PCB are marketing widely. The cost of this board is varying as per the distributor. I found the Skathi board are available but the coastwise I don’t like the product.
So that reason I like to build my own mono transistor amplifier board. The same circuit is implemented in Sakthi boards, I referred this circuit and PCB layout from videorockola website.
The amplifier is very cheap to build but the performance is awesome as compared with any other Audio amplifier. Because the power transistor 2SC5200/TTA5200 and 2SA1943/TTA1943 is using. The complimentary audio power transistors can drive very good audio output. The working frequency is starts from 5hz to 200 khz nearly. So building this kind of Audio amplifier is the better choice for car and home subwoofer amplifier.

Yes you can use but the power will be changes in the output
Thank for sharing your experience, sir
