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 manufacture your project are freely available for use and modification from the link below.

Updated 14/08/2019: The BOM now includes the missing SMD resistor and placement details for components.

The link here seems to download the chipamp.com gerber, not the 00940 gerber.
Hi Mark,
Apologies, I had to renew all my links and it seems I got some mixed up. You should be able to get the 00940 one now.
Hey,
No worries. Thank you for providing the files and fixing it so quickly! 🙂
