The Boozhound Labs pre-amp I built needed a power supply. The basic option was just to use a basic “wall wart” DC power supply, but knew these were generally low quality, unregulated and quite noisy. Since pre-amp quality is pretty dependent upon power supply quality, I decided I wanted to use something better.
I found a project by AMB Labs for a Sigma 11 power supply. It’s a high-quality regulated single-rail power supply. I’d configure it for 24v.
Here are the images of the completed build.
