Build this passively equalized RIAA phono preamplifier.

This project is based on Analog Devices' Audio Systems Application Guide for RIAA Phono Preamplifiers. The design includes an equalization network specifically optimized for RIAA phono reproduction. With the specified component values, the preamp can accurately recreate the three RIAA de-emphasis time constants of 3180 uS, 318 uS, and 75 uS, which also correspond to the frequencies 50 Hz, 500 Hz, and 2122 Hz, respectively. These are essential for ensuring accurate reproduction of sound from vinyl records Listening to the prototype with Michael Jackson's "Thriller" and Fleetwood Mac's "Rumors" vinyl LP album records, the audio quality is warmer and more real than the CD version that I also own. This is due to the analog nature of vinyl records, which preserve the original sound without compression, unlike digital formats, resulting in a richer and more refined listening experience.
