The Sovtek 5881 delivers a warm, round tone that “sweetens” any vintage or modern guitar amp design. Chances are if an amp uses 6L6-style output tubes, it has Sovtek 5881’s in its sockets. 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 5881/6L6WGC is probably the most reliable current production 6L6 available. Used by Marshall, Soldano, Solo, and others. The Sovtek 5881 has a heater voltage of 6.3 volts at 0.88 amperes. Maximum plate voltage is 250 volts while maximum plate current is 73 mA.

We have these in stock in Yorkshire in the UK
We also offer a 120 day from purchase warranty on the product ( excludes user caused mechanical damage failure and incorrectly set bias ). Make sure the bias checked and set correctly.
Note: Valves use high voltages and these voltages are dangerous. The amp can still retain these high voltages for some time even after being switched off. If you are not sure of fitting them , please seek the services of qualified personnel
