The amplifier is easy to build, and very useful. This is not the latest version we can modify it to get more power.

Some safety circuit is required to protect op amps when signal became too strong or power suply voltage decrease from heavy load. If voltage signal rise above power supply level large input resistance of follower disapear completely and almost half ampere of base curent will be drawn from driving op amp

There's a little bit of clipping on the negative half of the waveform, this is gonna cause hearable distortion. I suggest changing the + - 15V supply rail to + - 20V for the op amps to fix this..
