Mohawk Munged. Part needed...?

[John]

       I've been slowly refinishing and restoring a Mohawk  I got from
fellow Heath fan, KD4CPL, and I'd noted great performance on all
bands but 40m. Occasionally on 40, the rig would just take off,
and not respond at all to movement of the main tuning dial.

        Tonight I started a careful alignment and peaking of the radio
and I found out why.... 160 aligned and peaked well... onto 80m...yup..
a little tweak and all is well. Now onto 40... align, OK... tracking ...pretty
good.. now peak the antenna coil... as soon as I touched the
tuning stud I heard a THUNK onto the bench and knew what I'd find
underneath.
        Yup! Part of the ferrite core fell from the coil. Looking
carefully>inside, I could see that the brass shaft had sheared some time
ago,>and the broken ends had actually turned greenish blue with oxidation nd
that the ferrite was now in 4 pieces.. At least now I know why the radio
was subject to uncontrollable flights of fancy, even though I'm
stuck as far as getting this thing aligned or playing on 40m.
I'm trying to unthread the remnants out of the core... (what's in there
is broken radially into 3'rds and is resisting all but the most patient
attempts to thread it out of the coil.... If I can get it out, I'll epoxy the
4 pieces back together..) but I think I'm going to need a replacement
from a donor Mohawk.

        Does anyone have a Mohawk that has been parted, that
might contain a core from one of the 5/16" diameter coils (the Antenna
Coils?). I'd greatly appreciate the assistance, and an otherwise
fine radio will be back on the air.

        A strange audio clipper mod, involving 2 6AL5's a 12AU7 and
a matching transformer was sucessfully excised, and the radio is
back the way it was designed... although this mod was nicely
done, it didn't seem to accomplish anything when Nick and I tested
it over at his place, and I'm happier with the radio back to stock. All of
the mods were done on a added subchassis , so the rest of the
radio was not hacked.

        If you can help me in any way in finding a replacement
core, I'll be very grateful, and the Marauder and its twin Mohawk
will hit the airwaves again.

        Thanks in advance,
        /John
