An easy to make class AB audio amp. The amplification is given by the diference of the two resistor 330k / 220k. The op amp cant give much current so the transistors boost it with  1.25:1 input output ratio after the op-amp. The transistors need to be matched pairs eg. TIP31 and TIP32. If you use transistors insted of diodes (A + AB) you can get 1.017:1 after op amp.
