What is frickelYAPPA?
frickelYAPPA is a phono preamp based on 4 LM833 operational amplifiers. The amplifier is powered by a 5V USB wall power supply via a micro-USB plug. Mechanical components like RCA jacks will be chassis mounted and wired to the terminal blocks.
The PCB measures 64mm x 60mm and features M3 mounting holes for mounting inside an enclosure. The operational amplifiers are, unlike shown in the KiCad 3D rendering, to be mounted inside DIP sockets. The following images are WIP snapshots and still contain errors.
