Put 741 amplifier schematic into any search engine and watch the circuits roll in. Separate from that, MrChips is right. For a basic audio amp, the 741 has too much baggage. A specialty audio amp chip is way less work, and the LM386 gets you 1-2 watts with very little effort. What is the application?
