I think if you use the search function you'll find about a zillion threads here with all the info you'd ever want

Here are some basics about power supplies:
Unregulated Power Supply Design
The short thread linked below should have everything else you need, in order to understand a simple power supply:
http://www.diyaudio.com/forums/power-supplies/170080-does-lm317-act-like-transformer.html
You will need a dual-polarity power supply, i.e. both a positive and a negative power supply, to run most chipamp chips. Here is one:
http://www.diyaudio.com/forums/chip-amps/56106-lm338-regulated-snubberized-psu-audio-amplifiers.html (but remove the short across the secondary of T2 in the diagram)
You could, instead, use an unregulated power supply, which would be simpler.
Also look to post #68 of that thread, to get an amplifier circuit. Make two of them.
Go to National.com and download the LM3886 datasheet to find the pin numbers that correspond to the connections in the diagram.
Parts can be purchasd from mouser.com, digikey.com, and many other places on line.
Do some more reading, here, first.
