I wouldn't call it very good, it can be improved in quite a few ways fairly easily.

The output resistors are labelled wrong. They should be 0.47 ohm not 47 ohm. Also the 10 ohm at the output should be 0.1 ohm.

I can't figure what the 270 ohm 1W + 47uF 40V cap is doing.

None of those things should stop it from working though, just make the output very quiet.
