JJ EF806-S |Needs sorting to get good specimens for demanding applications


JJ-EF806 is a pretty good tube, the only thing missing is EF86 marking because it is not near specifications of real EF806. Requires sorting to get low noise and tight bias as all tubes of this type should have. Microphonics are not an issue in combo amps, so we finally have an EF86 type that works at this conditions.

A very nice EF86


I'm currently trying this tube out in a Leak Varislope Stereo pre-amp, and it sounds great. They are very similar in sound to the Siemens EF86 that I'm also testing.
