- Description
- Specifications
The 50Y6 (and 50Y6GT) is an 8-pin octal dual diode high-vacuum rectifier designed for power supply service in transformerless AC/DC radios, voltage doubler circuits, and compact audio equipment. Operating on a 50V heater rated at 150mA for series-filament strings, it features independent cathode connections for flexible circuit configuration. It was a common component in mid-century tabletop receivers and audio gear produced by Zenith, Philco, RCA Victor, and Admiral. Available in NOS and tested used conditions.
