GE 5Y3GT Rectifier Tube (NOS Vintage)
The GE 5Y3GT is a classic American rectifier tube known for its smooth voltage sag, warm feel, and rock-solid reliability. Built by General Electric during the golden age of U.S. tube manufacturing, this is the rectifier that helped define the response of early Fender tweed amps and countless vintage hi-fi circuits.
In guitar amps, the 5Y3GT delivers a softer attack and natural compression compared to stiffer rectifiers, giving notes a touch of bloom and that unmistakable vintage “give.” It’s a big part of why small tweed amps feel alive under your fingers. In hi-fi gear, it’s prized for its smooth, noise-free operation and long service life.
