and matching 1-64 hex nuts. Place the speaker into its position on the
backside of the front panel between the power and squelch knobs with the
speaker wires going up toward the top of the case. They're going to loop
over the front panel when we connect it later. Attach the speaker to the
front panel using the screws and nuts, screws coming in from the front
panel and nuts on the backside to look nice and neat.
148. Place the front panel with the speaker into the bezel so that the bezel
can be screwed to the case bottom. The bezel has a smooth side and a
side with ridges on it. The smooth side is where you place your front panel
and the ridged side fits into the case bottom; the ridges help align the
bezel and panel.
149. Take the bottom of your case assembly and the front panel/bezel
combo, along with the screws that hold the front panel to the case bottom.
Screw the front panel assembly to the case bottom.
150. Once you have the front panel attached to the case bottom you can
take your attached but not yet soldered PC boards and slide them into the
case bottom. Carefully line up the switches and potentiometers so that
they extend out through the front of the case. When everything is neat
and right where you want it to be, take your soldering iron and solder one
of the pins of either J5 or J3 (J5 is easier to get to). You'll note that J5 is
labeled J6 on the front panel and J3 is labeled J2 on the front.
151. Check the alignment one more time because once you make the
next solder connection it will be difficult to take the boards apart again.
Make sure the front panel board is flat and not angled with respect to the
main board, make sure the pots stick out enough and that everything is
right, then solder a pin on J3 to hold things in place.
152. Slide the main board out of the case bottom carefully and continue to
solder both sides of J3 and J5 until all connections are made.
153. Once the connections are soldered you can slip the board back into
the case and plug the speaker in. If you're looking at the board so that you
can read the silkscreen for SP1, the side of the connector with the red
wire should be place to the left on the pin that's marked with a white
arrow.
154. Now carefully slide the top cover into place, remembering to keep
your speaker wires from getting pinched.
155. Take your rear panel bezel and plate, put them together as you did
the front panel, and screw them into place.
You're finished! Well, just about. You still will want to check over your solder
joints to be sure they're clean and well made. Take a look at the ICs to be
