Sylvania 5V4GA Rectifier Tube

The Sylvania 5V4GA is a full-wave indirectly heated vacuum tube rectifier, commonly used in vintage audio equipment and guitar amplifiers. It features a slow warm-up time, which helps protect other components by reducing inrush current. Known for its reliable performance and smooth voltage regulation, the 5V4GA delivers a softer, more musical response compared to solid-state rectifiers, contributing to the warm tonal character prized in tube amplifiers.
