Electronics Project Circuit Built in December

I built some electronics circuit over the Christmas holiday, I will post some of the circuit here as a means of paper reduction strategy (personal reference purpose) and for any interested person on the internet. Most of the circuit are modification of circuit I found out in IC datasheet manual, the Internet and text.

One of the project was a stereo power amplifier for my mobile phone. See Fig. 1.0 below for schematic
