Psu brick
About the Psu brick PCB
Psu brick is an open source PCB design by josko7452, published on GitHub. It is a 2-layer board measuring 114 × 60 mm, with 16 components from 10 distinct parts.
By type, the board carries 7 capacitors, 2 connectors, 2 fuses, 2 diodes and 2 resistors.
From the project
Low noise RIAA preamplifier with JFET input and active input impedance (to mitigate Johnson noise)

To build this just download Gerbers from release page and hand-off to your favourtie PCB manufacturer. I have tested it with JLC PCB. But it has no crazy requirements besides the mainboard is 4 layer.
