6L6 - 5881 -KT66 - 7027
Shop our large selection of 6L6 & equivalent vacuum tubes. This is one of the most popular power tubes on the planet and as such, there are almost unlimited options.
There is much confusion surrounding the equivalent and substitute tubes in regards to 6L6. Much of it has to do with the fact that the tube has been around for so long, it has been revised and new versions have been made. Please be sure that you are ordering the correct tube. A 6L6G will not work in place of it's high-power successor, the 6L6GC.
When in doubt, you can always use a 6l6GC if an amplifier calls for any of the 6L6 types because the GC can handle the highest voltage.
