GainClone Chipamp Audio Amplifier

Gainclone or chipamp is a type of audio amplifier made by do-it-yourselfers, or individuals interested in DIY audio. It is a design based on high-power integrated circuits, particularly the National Semiconductor Overture series.

“The amp is based on the Project 19 PCB, so uses a pair of LM3876 (or LM3886) power opamps, run from a ±35V supply. ………..The power supply is conventional in almost all respects. I used a 160VA transformer, a 400V 35A bridge rectifier, and a total of 20,000uF per supply rail – 4 x 10,000uF caps in all.”

“The Gainclone amplifier has proved very popular with hobbyists since construction is straightforward and the resulting amplifier has an impressive performance specification.

A Gainclone for the PC Age

Most designs discussed online are aimed at audiophile applications. Here is a design for connection the a PC. It powers up and down with the PC and audio input can optionally be taken over USB.”

“But it was the Gaincard that caught the imagination of audio diy-ers around the world and before long, copies of the Gaincard were appearing on internet sites and discussion forums. The Gainclone was born!”

“I had previously planned to build a small stereo amp using the amp6 kit from 41hz.com. After deciding I wanted a bit more power, I did some research and am now going to build a so-called gainclone amp based on the LM3886 chip.”

“First, check out this 3-channel buffer amp Darcy made! It uses the chipamp.com LM3886 amp boards! Feel free to send pictures of your amp and we’ll show them off for you.”
