Class B amp with PSU

A bit slow to start. (Not very slow any more.)

I don't think it qualifies as hi-fi, the ripples in the power lines are visible in the output.

Tweaked for headroom and efficiency, and input increased. Slower to start again, but EC's current dots are more interesting. Output about 8W now.

Errr... XD I don't know what it's capable of, but it's only pushing 80mW right now.

Changing only the signal voltage, it's capable of 6 or 7 watts before distortion starts.

Removed. Didn't hurt at all.

Today I learned it wastes a lot of power, nearly 900mA with no input. That's maybe 80% of what it puts into the speaker. It needs better biassing.
