In FIG02, we see three stages, an Input stage (or Diff Amp, or LTP (Long Tailed Pair)), a 2nd stage (also known as the Voltage Amplifier Stage or VAS, and a class AB output stage. Actually this diagram is that of an op amp, but as we will see an audio power amp is an oversized copy of the same device. (fig 02)
