Builder's report

RCA-RIAA successor

by Carsten Rauth (carawu) · written in German

Phono and RIAA

A phono stage built on Thorsten's cheap valve RIAA design, which he developed to avoid the problems of the classic RCA RIAA circuit: an ECC88 second stage, a semi-split RIAA network, and no cathode bypass capacitor in the first stage. Includes grounding and parts notes.
