Blackburn EL34

About the Blackburn EL34

The Mullard EL34 tubes are celebrated for their musicality and durability. They are often used in high-end amplifiers to enhance sound quality. The Xf2 model, produced in the 1960s, features welded plates and a double ring getter, while the Xf3 model, from the mid-1970s, has stapled plates and a single halo getter. The Xf4 model, introduced later, is distinguished by having only four dents in the mica spacer. These tubes are highly sought after due to their superior performance compared to modern Chinese or Russian alternatives.
