After reading "Jones" Valve Amplifiers I laid in a stock of them ...
Please keep this quiet elst we have to sell them to 888 land.
You can try with 5879, audio pre-amplifier use, this tube is the good replacement for EF86.

It really is sad there are no more small signal pentodes being made (as far as I know). I tend to like the sound in music amps quite a bit, esp. for guitar.
e80f is not really a direct sub for ef86. It would sound much better than EF86 in the appropriate circuit, but dropped right in I am not sure things are ideal. Apparently there's a few predecessors of this tube that have different naming, but they were designed for EEG pickups and other small signal stuff (for what that's worth).
5879 is a great sounding pentode too, but I've always seen them in spring mounts with steel shields. Might as well call them microphones instead of pentodes, but I've only seen a limited sample set. Somewhat similar sound to EF86 (apples and oranges I know).
Don't forget 6sj7, the octal audio pentode. Good sonics but like the 5879 makes a good microphone. Never tried it for music listening, just for music playing though.
Anyone heard or used a 6L7 for anything? The old RCA books seem to like 'em a lot for various strange audio purposes. If I recall correctly it's a heptode...
