Step 10: Mounting part 2

B. Flip module over and place on a hard surface or in vise to solder. (see photo above)

C. Now solder one joint on each component:

• One lead of each LED (either one)

• The center pin of each 16mm and 9mm potentiometer

• Either the left or right lug pin of each 9mm potentiometer

D. Flip the unit over and tighten down the potentiometer nuts with your 3/8" driver or pliers. Now install

the 4 knobs on the pot shafts. Notice how the pot shafts have a D shape, as well as the inside of the

knob.

E. Move each knob so that it's centered within the panel artwork (see

photo on right). If the center detent of the pot does not match the center

point on the panel silkscreen (in this case the noon hashmark, see

photo), you may have to loosen the pot nut and reposition it. Try

holding or pushing the shaft of the pot in the direction you need it

tweaked, while tightening down, using your needlenose pliers, with the

other hand. If you have trouble pulling the knobs up by hand to loosen

the pot nuts, you may have to pry them up with a tool. If this is the case

make sure you don't scratch the panel, or damage the knobs. A small

screwdriver acting as a lever with a soft cloth underneath to prevent

scratching of the panel should suffice.

F. Move each 9mm potentiometer and make sure it is centered on the O

mark (see photo on right). If not, heat up the pin you soldered in step

10C, and center the pot with your hand. It will help to hold the module in

your hands rather than against a surface or in a vise.

G. Verify that each LED is visible through its hole in the panel. If

necessary, re-position by heating up the one pin you soldered in step

10C.

H. Verify that your four switches are not poking out of the PCB.

I. When you're sure all the pots, jacks, switches and LEDs are all placed perfectly, you can go ahead and

tighten all the nuts down (careful not to scratch the panel!)

J. Check all the pots, buttons, and LEDs a third and final time, and then flip the unit over and solder the

rest of the PCB (all jacks, pots, buttons, and LEDs). Snip the LED leads short.

A. Hold the unit so the panel is facing the floor. Gently guide the LEDs by

their leads so their heads fit flush into the holes in the panel (see photo on

left). Once positioned, you may want to slightly splay their leads so they

stay in place.
