I'd really like a stereo input selector with relays, but those things are hard to find! (Apart from some of dubious quality on the *Bay)
Better make my own then. This one's got a custom footprint for an ESP32 devkit module, but it can also be controlled with a rotary switch.
I've been getting my new hobby room ready, and I knew I needed some kind of stereo system in there. Preferably one that didn't annoy others in the house, so I ended up ordering PCBs from Nwavguy's gerber files. Yup, I'm gonna use headphones. :)
Here's the finished Inverse RIAA. I haven't done extensive testing yet, but it works as promised AND it measures exactly the same on both channels. I'm really happy with the result.

This is my first venture into SMD components, so I'm going to have some fun with tools, solder paste, stencils and hot air. :)

There are several ways to make your own Muffsy Phono Preamp, but the power supply has been missing. Until now. Below are both gerbers and PDFs that allows you to order or etch your own power supply boards.
