Thirty years ago I used 6DJ8 (E88CC) to solve a third order IMD problem with
tuned loop that was using J310s.
The IMD was caused by Radio Free Europe on 13m.

Of course, a 12AT7, or better, a 6DJ8, would be excellent preamps as
well,
and aren't so sensitive to transients etc. :-) (Showing my age, I
guess!)

As far as am aware On-Semi still make the TO-92 J310. Fairchild ceased
production about 2 years back. I did a last time buy from Mouser for
several
thousand J310 and the much more linear J309.
