Q107:
MFE131 transistor
(#417-863). Match
the tab on
the transistor with
the
outline of
the tab on the
circuit board. Then
insert
the
leads into
their corresponding
holes,
position
the transistor
1/4"
above
the circuit
board,
and
solder the leads
to the foils.
Cut off
any excess
lead lengths.
Install parts in Section 4 of
the circuit board
as
fol-
lows.
Solder the leads of each part
to the foil as you
install it and
cut
off any
excess lead lengths.

(Illustration
Booklet, Page

for
the following steps.
Install
parts in the circuit
board as follows. Solder
each part to the foil
as you install it and
cut
off
any
excess
lead lengths.
NOTE: When
you
install
a control on the circuit
board, start the lugs of
the control into their circuit
board holes and push the control down
tight against
the circuit board. Then solder
the lugs to the foil.

L118:
5.5
n,H
coil
(#40-2111). Match
the
color
dot near one
lug of
the coil
with the
dot mark
on the
circuit
board
and start
the
lugs into
their
corresponding
holes. Push
the
coil down
tight
against the
circuit
board,
solder the
lugs
to
the foil,
and cut
off any excess
lug
lengths.
NOTE:
You may
have
to straighten
the
lugs
on
this coil
to make it
fit the
circuit
board
holes.
