This repository contains a KiCad project for an open-source RIAA equalization circuit to be used in the Beogram 4002 turntable.
The project is, for now, a prototype in progress since I need to gain knowledge about audio circuits and operational amplifiers while developing it.
The RIAA is based on a two-stage RIAA using the LM833 which should greatly improve the performance over a singleamplifier design.
- Two-stage gain.
- Low noise.
- Plug'n'Play / Drop-in replacement.
- ...
- Finish the schematics for the prototype.
- Finish the PCB design for the prototype. -Test the RIAA with adequate equipment.
