Eurorack DIY: Power supply interference 

The Schematic Diagram, BOM and Gerber-files is avalable on my GitHub: github.com/tkilla64/eurorack/tree/main/misc/psu_filter

Wow I didn't expect that rate of noise you had before the filter ! Well played, really inspirating to get clean and proper mastering

Top work, Tommy! I love that approach - to actually fix things rather than switching system parts. Excellent video.

For 10 years I have only ever used the expensive Doepfer or Clocks PSU (all around 180,--). Until 8 years ago, when I got a tip from a DIY Eurorack Master builder who only uses MW RT-65B. Since then, I don't put any expensive PSU in my self-built racks because it's unnecessary. The Meanwhell RT-65B is first class and costs only 25,--. No interference, no humming, no noise, very stable hosting, very stable bus boards which you can recognise by testing the OSCs. I can only recommend it to everyone.

is this problem common in other MW PSUs like the common 65B?

Do you have recommended reading on inductor part selection? I'm building a larger rack with about 8A positive and 5A negative. I'll be using some hefty TDK Lambda 12V 10A power supplies, but not sure on the ripple yet

Lokk at that. All done and ready to go

Please could you telle where you sourced the inductors? I've tried mouser/element14/lcsc and can't seem to find them.

Would you be able to say whether this would work with the meanwell RT-65b that is also very popular in Eurorack? Also, what if multiple units are utilised in the same rack??

This is just wonderful. Ive been struggling with noise in my video synth, and im wondering if this might be an optional alternative to replacing the entire power system for something that runs alot cleaner.

Do you have a GitHub for this filter board?
