Beam Power Tube
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 is the most reliable, cost effective,
current production 6L6 available. They are used by
Marshall, Soldano, Solo, and others.
The Sovtek 5881 / 6L6WGC Vacuum tubes are a glass octal
type and are also used in the output stages of radio
receivers and high-fedelity audio amplifiers. They are
also used quite extensively in guitar amplification.
5881 / 6L6WGC tubes require an octal socket.
