"After I built several LM3875 and LM3886 gainclone amplifiers, I was totally impressed by their audiophile sound quality. Then I saw the Jeff Rowland Power Amplifiers that use LM3886, I decided to create my own version - the BPA300. My design goal is to create a audio power amplifier that can deliver 300W into my 4-ohm DIY speaker with low distortion. I want it to produce deep, tight and punchy bass while keeping the excellent mids and highs from my other gainclones." |

Very nice! Can you tell me where I can purchase the PCB's and schematics to Parallel-bridge my own LM3886? This appears to have a regulated power supply, what is the voltage at the rails as well as the Amps it will draw?
Sincerely,
Jeff Miller

Hi Jeff,
Just a cool article, it wasn't built by me. You can find more details here.
