Download the schematic. Study the power supply first, then the feedback network. Build it with high-quality passive components. And never, ever probe the B+ with two hands—that 250V will remind you why we respect tube circuits.
The represents one of the most influential circuit designs in the history of professional audio . Originally developed in 1960 by Bill Putnam Sr. , the 610 was the first modular recording console channel strip, defining the "tube sound" for generations of legendary recordings. The Original 610-A Circuit Architecture Ua 610 Schematic
Where modern schematics chase low distortion and flat frequency response, the UA 610 schematic creates harmonic complexity. Download the schematic
