Sheldon built me a PCB board that I have sitting around, and I want to make it, but before I do, I was wondering how hard it would be to convert to a power amp?

Hello,

Supposedly, it pushes out couple watts. Perhaps, use bigger and "bader" complementary pairs operated at higher voltages? Or you can perhaps parallel few more complementary pairs?
