Sovtek Tubes are used in many of the most popular guitar amplifiers manufactured today.

The Sovtek 5881WXT is the same as the 5881 but with a full size base for easy installation in vintage amp designs
The Sovtek 5881 delivers a warm, round tone that "sweetens" any vintage or modern guitar amp design
Built to rigid military standards, the 5881 will tolerate higher voltages than any other 6L6
In fact, they're frequently used as replacements for the old 7027 model in vintage Ampegs
Extremely consistent from piece to piece
