BOTTOM COVER ASSEMBLY
Attach
two
rubber
feet
at
the
rear
left
and
right
corners.
These
feet
are
3/4"
diameter
x
3/8"
high
with
domed
top.
Install
each
with
a
single
#6
x
5/8"
sheet
metal
screw
with
a
plastic
spacer
(5/8"
diameter
x
1/8")
between
the
foot
and
the
bottom
cover.
Tighten
the
screws
just
enough
to
keep
the
feet
from
being
loose.
Excessive
tightening
may
cause
the
screw
to
short
to
a
terminal
inside.
The retractable bail mounts with the two molded plastic feet attached with
two #6 x 5/8" sheet metal screws. Note that there is a difference between
these feet - "left" and a "right" style. Place each over their respective
mounting holes in the bottom cover and with the vertical notches facing to-
ward the center of the cover. The flat relief surfaces at one side of the
notches should be toward the rear. Attach one foot with two screws and tighten.
Now lay the wire bail flat on the bottom surface with the right angle feet
toward the front edge. Slide one foot in the plastic foot that you just at-
tached. (You may have to loosen the screws to allow the bail to enter --
retighten.) Next attach the other foot by placing it over that end of the
bail. The bail should be snug in its retracted position and should swing up-
ward and lock in the vertical position.
Mount the variable capacitor and the variable inductor to the inside of the
bottom cover via the four holes provided. Use 6-32 x 3/8" machine screws
through the bottom plate and mounting feet of each unit. Secure with a lock
washer and hex nut. The capacitor locates to the left with the 1/4" round
shaft toward the front. The variable inductor mounts over the two holes on
the right side. The coil end with the wide-spaced turns is toward the rear.
SIDE PLATES ASSEMBLY AND INSTALLATION
The two unpainted aluminum side plates (10" x 4-1/4") provide a means to at-
tach the top and bottom covers and also to anchor the rear panel assembly and
the front subpanel.
Place the side panels on the bench beforeyou with the long dimension to the
left and right. Position them so that the two square holes above and below
are closest to the right hand end. Now locate the small (3/16") round hole
near to one of the square holes. This small hole should be located to the
upper left of the square hole. If this position does not agree, turn the
panel over so that the position does agree.
Locate the eight spacer nut/spacer clips in the parts kit. These are U-shap-
ed clips that have two flanges on one surface and a speed nut perforation on
the other surface. These spacer nuts attach to the side panels in paper
clip fashion through the square holes so that the holes in the clips locate
over the 9/32" round holes adjacent to each square hole.
Install four clips on each of the panels (one through each square hole).
CAUTION: . Install so that all 1/2" x 5/32" parallel spacer flanges are on
the same side of each panel. Be sure that the flanges are on surface facing
up when the panel is located as in "2" above.
Attach the clips so that they fully engage the panel -- edges of the square
holes are at the full depth of the U-bend.
Attach one plate to the right side lip of the bottom cover using two black
10-24 x 1/2" machine screws with flat #10 nylon washers between the screw
heads .and the painted right side lip of the bottom cover. CAUTION: Remember
that the square holes nearest the end of the panel locate to the rear. The
spacer flanges go between the side lip and the end panel. The 3/16" round
hole should be positioned to the upper left of the upper rear square hole
when viewed from the outside of the tuner bottom plate.
Attach the remaining (left) side plate to the left side lip of the bottom
cover in like manner except that the position of the 3/16" hole is of no con-
sequence since it has no function on the left 6nd plate.
