Vacuum Tube - 5881WXT, Sovtek

Starting at: $23.65
In Stock

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. The Sovtek 5881 has a heater voltage of 6.3 volts at 0.88 amperes.

We can put together a matched quad in low, medium, or high. Simply send us a note when you place your order.

Our Sovtek 5881WXT tubes are Apex matched, which provides ratings for "Current" and "Transconductance" and would not have our tube sets labeled with "GM" and "LP." We are unable to speak about other matching services and the numbers they use. Using general terms like low, medium, and high numbers will be sufficient for us to be able to understand what you need and pull accordingly.
