This is a Genalex Gold Lion KT66 re-issue made in Russia. This tube boasts the same form factor as Chinese or Groove Tubes KT66. Gold Lion KT66 is built to last with durable and high quality construction.

In guitar amps, the Gold Lion KT66 has the roar that's expected of KT66 tube types, but it carries it to bigger volume really well. On audio amps, KT66 Gold Lion is articulate and is a step above other KT66/6L6GC types in sound stage imaging.
