5V4 Vacuum Tube New and Used

- Description
- Specifications
The 5V4 is an indirectly heated octal-base full-wave power rectifier designed for audio amplifiers, radio chassis, and television power supply circuits. Featuring an unipotential cathode structure, it provides slow warm-up characteristics that protect power supply filter capacitors from high-voltage initial surges. Operating on a 5.0V/2.0A filament, it was specified in mid-century radio equipment and hi-fi audio gear produced by manufacturers such as RCA Victor, Zenith, Philco, and Fisher. Available in NOS and tested used conditions.
