Yes this amp work, its base on quasi comp design, i`ll post pcb and artwork, i think i have it, u can add more output transistor for low ohm speaker, its scale able amp.
A bit of advice for blackpower - if you are going to post someone's schematics anywhere on the internet that are not yours, please be so kind and write whose schematics those are or give a link to that persons website if any. In other words, give credit where credit is due.
yep luchni, maybe blackpower forgot about it, its ok everyone almost know regarding that amp design popular on the net. for darezk buit this amp with care, its not for beginner but yes its powerfull.
I've already built this amp! it works and powerfull too, you can increase the output transistors if you want to drive it into a 2 ohm load and then it will deliver around 900 watt.
