the
circuit board.

Be sure you
installed
resistor
in
Pictorial 1-1 (Page 11).

R105B: 1.5
0 (Brn-Grn-Gold).
NOTE: Your circuit board
may
be
marked 33 at
this
location.
R104A: 1000
0 (Brn-Blk-Red).
R105A: 1.5
tf
(Brn-Crn-Go1d).
NOTE: Your circuit board
may
be
33
at
this
location.
Solder the leads to
the
foil
and
cut
off the excess
lead
lengths
.
NOTE: When you install a diode, al-
ways
match
the
band
on the
diode
with
the
band
mark on
the
circuit board. A
DIODE
WILL
NOT WORK PROPERLY
IF
IT
IS
INSTALLED BACKWARDS.

If
your
diode
has a solid
body
,
the
band
is clearly defined.
If
your
diode
has a
glass
body
,
do
not mistake the colored
end
inside
the diode for the
banded
end
. Look for a
band
painted
on
the
outside
of the glass.
