What Class of amp is it? Does it require polarized capacitors? By chance, we've all done it, are the PNP and NPN transistors inadvertently swapped? Did you search EC for audio amps by whatever name this one is called? Which part isn't working? And @yolibones, 4+ hours and two circuits is pretty harsh evaluation of such an app, not saying it's flawless, cause it's not.

I believe it might be a class b or ab amplifyer. This is purely what I found I found on the schematic but I'll mess around with some of the transistors and try to figure it out. @wyoelk
