Hi all,

The following comes from the preliminary R-391 manual (seem to
be the same as my preliminary R-390 manual in my lap):


I believe these three cores are the main ones used in the the RF deck
Tuner Assemblies.  Note that this is almost certainly ONLY for the
R-390/391 no-mod RF deck.  The Mod 1 RF deck has different slugs, and
probably FOUR different types:

    CORE, adjustable tuning: iron; 21/2" lg x 1/4"        Tuning slugs for Z202, Z208,
    dia w/one .062" dia phosphor bronze shaft             Z214, T202, Z201, Z207,
    7/a" Ig o/a; Stackpole mfg type S-51.                 Z213, T201, Z203, Z209,
                                                          Z215, and T203.

    CORE, adjustable tuning: iron; 21/2" lg x 1/4"        Tuning slug for Z204, Z210,
    dia w/one .062" dia phosphor bronze shaft             Z216, T204, Z222, Z223,
    7/8" lg o/a; Stackpole mfg type S-62.                 and Z224.

    CORE, adjustable tuning: iron; 21/s" lg x 1/4"        Tuning slug for Z205, Z211,
    dia w/one .062" dia phosphor bronze shaft             Z217, T205, Z206, Z212,
    7/8" lg o/a; Stackpole mfg type S-100A.               Z218, T206, Z219, Z220,
                                                          and Z221.
