This repository hosts a KiCad project for an open-source RIAA equalization circuit designed for use with the BeoGram 4002 turntable.
Currently, the project is a work in progress, serving as a prototype while I expand my understanding of audio circuits and operational amplifiers during development.
The design features a dual-stage RIAA equalization circuit based on the LM833 but with the OPA2134.
Contributions are welcome and much wanted! Whether you have suggestions for improvements, bug fixes, or additional features, feel free to submit a pull request.
