Begin by carefully emptying the contents of the parts envelope into a broad soup bowl, as
shown below. In general, you’ll start with the components that lay closest to the board,
working your way towards the taller components. You will:
1.
Install the resistors
2.
Install the capacitors
3.
Install the transistors
Component Order
You’ll notice that the component designations in the directions don’t go exactly in order.
We have grouped them so that all components with the same value appear together. This
makes assembly easier. You’ll find in the parts kit that similar parts, e.g. 3 1K resistors,
are typically (though not always) taped together.
Install the Resistors
In general, you install the resistors by placing the body on silk screen side of the board,
and the leads through the indicated holes. Bend the leads over on the back of the board to
keep the resistors from falling out until you solder them in place. Try to bend the leads in
a direction that won’t lead to solder bridges between traces that should remain
disconnected.
Figure 2-Installing resistors
We recommend the following procedure:
1.
Insert all the resistors of the same value, e.g. R4 and R7.
2.
Bend the leads as described above.
3.
Solder the leads on the back of the board.
4.
Clip the leads.
Track your progress by placing a check-mark in the done column as you install each
resistor. Check resistor values with a meter, or by reading the color code
