For sale are AC mains filter PCBs. Relative low parts count results in a very good filtering. I used many in the DIY projects I built for myself and several friends. Can be built for up to 6A Chokes by Schaffner but I usually used it in low amps circuits like my Soekris DAC or Shigaclone.
Currently around 10-12 PCBs at hand, asking 6€ per PCB + shipping + PP

Example build:

Need to check on my Computer. Though that might no longer be there cause the original design is older then my PC 😂
Back then it was compared to standard Schaffner Emi filters and some „vodoo audiophile power strips with filters“ and it performed better in every test. It averaged around 20-32dB less noise.
