About the Panels PCB
Panels is an open source PCB design by josko7452, published on GitHub. It is a 2-layer board measuring 103 × 63 mm, with 14 components from 9 distinct parts.
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.
