Laeeq; You can find a nice amplifier IC schematic at http://www.datasheetcatalog.org/datasheet/philips/TDA7052_CNV_2.pdf . Copy this address and paste into the address box and then look at page 6 in the pdf for the schematic. The chip is cheap and many suppliers have it. Mouser has it for $1.14 US. Order TDA7052AN. If you can’t find this chip you can always find plenty of info on the LM386, which is the industry standard for low-voltage/power amps.
