Quite a range you can do for a simple IC driven amp..

Top quality...use national semi's LM4702 with MOSFET
or darlington..
mosfet..
www.national.com/an/AN/AN-1645.pdf

darlington...
www.national.com/pf/LM/LM4702.html

or browse all the amps (some discrete ones are super simple ,too)
http://71.203.210.93/pdf1/Electronic...cts/Audio_amp/

Or along the lines of a 741 based one (like yours)
(see attached)
