5V4GA SYLVANIA NOS Black Plates Halo Getter Rectifier Tube Made in USA

Description:

The 5V4GA SYLVANIA NOS is a high-quality full-wave rectifier tube, manufactured in the USA according to the most stringent industry standards of the golden age of the vacuum tube. This version with black plates and halo getter represents one of Sylvania's most prized achievements for its operational stability, long-term reliability, and controlled electrical behavior.

This is a NOS (New Old Stock) model, never used, carefully tested in our laboratory to ensure performance fully compliant with the original specifications. The robust construction and attention to materials make it ideal for high-quality hi-fi applications and for philologically correct restorations of vintage American equipment.
