This is the original chipamp.com board for the LM3886 amplifier, generously released into the public domain by its designer Brian Bell. The board size is 30x74mm so comes in really cheap when ordering. Although the schematic is provided below, it is also worth having a look at the datasheet for more information. Click here to…

LM3886 Amplifier Build Files by 00940
A thread on DIYAudio was concerned with creating an open source PCB layout for the LM3886 amplifier. Although initiated and largely designed by user 00940, there has been some input from others, including advice from Tom Christiansen of Neurochrome, resulting in this implementation. Gerber files, the set of files necessary for a PCB lab to…

An open source LM3886 chip amplifier.
I decided to build an amplifier for a friend. There are a number of good chips for amplifiers and I managed to purchase a pair of LM3886 opamps new for £5 from a seller on DIYAudio a few months ago. With the chip decided upon, a suitable layout was sought. As much as I would…
Attack of the Clones
What does a $3300 amplifier sound like? I suppose I’ll find out soon when I finish building a Gainclone amplifier. A Gainclone, as its name suggests, is a clone of an amplifier which first appeared in 1999, the Gaincard built by 47Labs. Heralded for its sound by Stereophile magazine, people were nonetheless surprised to discover…
