I would not reccommend single sided boards for class d.

If you cant find double sided copper clad where you live, you might wanna consider letting a boardhouse make the boards.

Two good ones are PCB Cart and Olimex.

Default Wow

Finally I got to work !

Its really powerful ! This is my first Class D amp.. even running it without a heat sink and there's no distortion in my PCB.. super efficient.. +/-25 dual supply .. I'm gonna increase the voltage step by step.. will let you know the result.

DO not follow My PCB.. caz It has a couple of errors.. This amp works fine without a dual layer board.. I'll send pictures of my dam amp.. Its like a garbage ..LOL still works fine.. I'll be finishing errors on my board and rebuild the amp..

I would say, dont worry people who wants to try this.. !! Its a fully working amp ! and the simplest class D amp ever I saw .. I'm really really happy .. may thanks for the designer !
