[Discussion/Interest Check] Reviving the Muffsy Phono Preamp: Who else would be interested in a community build or kit?
Hello r/diyelectronics,
I know the Muffsy phono preamp has been a very popular design in the DIY audio community for years—it's a fantastic, transparent circuit. However, with the official kits often being unavailable or out of stock, I know a lot of people have been waiting to build one.
A quick note on the design: The original creator was incredibly generous and made the schematics and BOM (Bill of Materials) openly available for anyone to build their own. I've been working on creating my own PCB layout and sourcing the components based on the publicly available design files, with the goal of creating my own version with board-mounted connectors.
My Question to the Community:
Before I commit the time and money to building a prototype and ordering parts, I'm trying to figure out if there is enough demand for this type of project.
Instead of keeping this project to myself, I'm considering putting together a small batch of PCBs and sourcing all the necessary components as a "group buy"—not for profit, but just to make it easier for other interested hobbyists to build one without the hassle of individually sourcing 50+ components.
I am not selling anything right now, and this is purely an interest check. I'm simply trying to find out: How many of you would genuinely be interested in putting together a kit like this yourself?
Any feedback on the idea or thoughts on features (e.g., preferred component mounting, enclosure ideas, etc.) would be greatly appreciated!
