5Y3G
5Y3G is a designation used for a vacuum tube rectifier produced in the mid-20th century. It is part of the 5Y3 family of high-voltage rectifier tubes and was manufactured by multiple companies, including RCA, Sylvania, and Tung-Sol. The "G" suffix typically indicates a glass-encased form factor, distinguishing it from other envelope designs used for related models such as 5Y3GT.
In operation, the tube functions as a rectifier, converting alternating current into pulsating direct current to
Variants and compatibility: The 5Y3 family includes several versions with similar electrical characteristics but different envelope
Present-day context: With the widespread adoption of solid-state rectifiers, 5Y3G is now largely obsolete for new
