This "project" was originally started sometime in 2010-2011 after a friend asked me if p channel devices could make an amp, i thought "why not?" and developed a circuit using only p channel mosfets in the output stage.
However the friend was unable to make the circuit work, so then i tried it, and after some fiddling around i managed to get it working, this was the results: http://www.youtube.com/watch?v=1tEMZtQUpDY
Shortly after that video was taken, i more or less put this project aside and eventually forgot about it, until a few days ago when i got a pm about it.
So i decided to revisit this old project, said and done, i repopulated the board from the old project with the components that had since been taken and hooked up two IRF9540's.

Power on, adjust dc offset and bias and done. This is the circuit if anyones interested in trying it: http://i.imgur.com/A5zLE.png
I ended up building a stereo version because it exceeded all my expectations: http://i.imgur.com/xROrl.jpg
