GainClones are quite popular with audio enthuiaists now a days. They provide cost effective and high quality solution for DIY home audio systems. A GainClone basically consists of an Audio Power Amplifier IC (most famous are LM1875 , LM3875, LM3886 & LM4780) in addition with basic discrete components like capacitors, resistors and inductors.
In this Blog I have shared my experiences during making a Gainclone amplifier of mine. And i got lot of help from other people from internet and especially DIY sites like DiyAudio and ESP Project Pages.
