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.
(If you want BOM, download KiCad and generate it from the Schematic, you will likely change parts anyway dependig on accessibility.. you can shoot me a message and I will send you the Mouser part list from my order history if you wish)
There are 3 KiCad project for each PCB. i.e. 'main-pcb', 'panels' and 'psu-brick'. Also there is LTSpice simulation in 'ltspice' subfolder. Other than that it also cointains KiCad libraries used as submodules (kicad-footprints and kicad-symbols)
