well, probably. I build a somewhat similar amp, without any pcb at my first try. It had no soic parts however, a mint isn't the easiest amp to begin with, I'd rather go for an amp with full size parts.
If you plan to begin in diy, you rather should try a cmoy first. It's less expensive if it fails. It is also a good way to see if you actually like electronic diy. Mint would be step n°2.
On the other hand, if you just want to get a mint cheaper, I'd rather buy an used one. Cost of tools and mistakes are too high.
