    They are all supposed to be the same. You may be better off modifying the circuit to get more gain out of the EF86 you have. Pentodes are versatile this way and it shouldn't be difficult. If I had a schematic of your unit I could make suggestions here.

    Who makes ANY EF86s today?

    I know the St. Petersburg Svetlana factory used to, but I'm not sure if it still does

    Blast the preamp with a treble booster. My matchless used to love the beano boost and the DAM stuff looks good. Cant wait to try my hayseed 30 on order. Oh yea get a mullard ef86 tube. NOS tubes sound great.

    I think they've given up. Probably the horrible reliabilty and relatively small market.

    NOS is the only game in town. EF86s in general have HUGE gain. The ciruit they're used in is the determining factor of how they operate.

    Yeah, I've seen those Russian EF86s with various noteworthy lablels. The dead giveaway is the "flying saucer" shaped getter.
