Learn how to bias fixed‑bias push‑pull tube amplifiers using the output transformer resistance method for precise idle current and plate dissipation. This step‑by‑step guide covers 2‑, 4‑, and 6‑tube power sections, explains all the math in plain language, and shows why this approach is safer than traditional shunt current measurements. It’s aimed at builders and techs who want repeatable, bench‑friendly results without needing an oscilloscope.
