I noticed this thread had been bumped, so I removed the links to  Rapid Share and uploaded the files here. Then I realised it was a spammer who'd bumped it so I deleted their post. I didn't want to have wasted my time so I bumped it anyway as it looks like a good project. Of course most people use ICs nowadays for audio amplifiers.

Of course it was a good project at Silicon Chip magazine about 7 years ago.
It is still a good amplifier project.
