Hold
the
PC-7
board
as
shown
in
the
pictorial,
with
the
I.F.
transformer
away
from
you,
and
carefully
pick
up
the
tuning
capacitor
C1,
holding
it
so
that
the
shaft
points
away
from
you.
Be
particularly
careful
that
you
do
not
touch
the
semicircular
cop-
per
and
aluminum
colored
plates
of
the
capacitor.
If
these
are
bent,
even
slightly,
it
will
be
difficult
to
get
the
tuner
to
track
accurately
across
the
dial
when
you
come
to
the
alignment
procedure.
Now
insert
the
small
tabs
which
protrude
from
the
bot-
tom
of
C1
into
the
corresponding
five holes
in
the
top
of
PC-7.
Be
careful
capacitor
C7 is
not
dam-
aged.
This
fit is
especially
snug,
but
be
sure
that
the
tuning
capacitor
is
fully
seated
against
the
board.
Two
of
the
threaded
studs
of
the
capacitor
will
also
engage
the
board.
The
shoulders
of
these
studs
should
seat
against
the
board.

Install
four
sets
of
#6
(medium
size)
lock-
washers
and
nuts
on
these
studs
but
do
not
tighten
them.

the
PC-7
board
in
place
with
five
sets
of
#4
(smallest
size
nickel
plated)
hardware.
Install
the
screws
from
the
top,
and
secure
with
a lock-
washer
under
each
nut.
Tighten
these,
and
also
tighten
the
nuts
on
the
capacitor
studs.

Unless
otherwise
specified,
the
insulation
should
be

of
insulation
from
the
other
end.
Feed
the

of
socket
V8
and
connect
it
to
pin
#l.
Keep
it
clear
of
pin
#2.
Solder
pins
#1
and
#3.
