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 axial leaded components (like the resistors) by placing the body on

the 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 your 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.

We recommend the following procedure:

1. Insert all components of the same value or type

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

component. Note that R14, a 2 Watt power resistor, will be installed in a later section.

Install the diodes

Diodes are polarized, having an anode and a cathode. When you insert the diode, match

the banded end of the diode to the banded end of its representation on the silk screen.

Refer to Figure 1 to see what diodes look like, and how they should be oriented.

2R49 is another way of writing 2.49 Ohms. The "R" takes the place of the decimal point. Note that this

resistor was 4.77 Ohms in Rev D and earlier. The change to 2.49 Ohms allows extra power to be delivered

to support the installation of the phono upgrade kit.
