Heathkit HD-1250 - Oscillator Circuit Board

OSCILLATOR CIRCUIT
BOARD
Position the oscillator
circuit board as
shown. Then proceed
with the following
steps.
( )
Cut
one lead
of
a
47 pF mica capacitor
to
1/4"
and cut the other
lead to
3/4".
Bend the longer lead
straight out, and
the
short lead toward
the side
as
shown.
>
1/4'
(
)
In the same manner, prepare another
47
pF
mica capacitor.
Bend
the
short
lead in the opposite direction
to
the
one in the previous step.
NOTE:
In the following steps,
push the
short capacitor lead into the
circuit board
hole. Position each
mica capacitor
flat on
the
circuit board as
shown. Then, solder
each capacitor to
the foil as you
mount it
and cut off the
excess lead
length.

Remove the
excess coating from the
leads of a .001
pF disc capacitor.
Then wrap the leads
of the capacitor
around the
leads of a 27 J2 (red-
violet-black) resistor as
shown.
Solder
the leads
as
shown
and cut
off the excess
resistor leads.
