NOTE:
In
the
following
steps,
bend
the
leads
of
the
10
wh
RF
choke
(#45-60)
to
reach
their
proper
connect-
ing
points,
then
cut
off
any
excess
lead
lengths.
Bend
the
leads
very
carefully
so
as
not
to
damage
the
coil
form.
Also,
do
not
allow
the
choke
to
extend
over
the
rear
edge
of
the
chassis.
( J At one end of the coil, connect lead 1 to lug 3

This
completes

Carefully
check
to
see
