Specifications

Here is where good soldering skills and attention to detail will pay off. By following these
directions, you should have no trouble in completing the circuit assembly quickly and without
errors.
I encourage you to first read all the steps to familiarize yourself with not only the installation
flow, but also the components to be used. Appendix A has explanations on how to read the
value codes found on both the resistors and capacitors. Appendix B has helpful hints on
improving your soldering skills.
Printed Circuit Board (PCB) Assembly
Installing the Components
This PC board was designed for both great tone and ease of assemble. This PC board
layout closely follows the original point-to-point layout in order to duplicate any tone shaping
created by component and wiring proximity interactions. Additionally, there are built-in
modification options available exclusively with this board. With over-sized traces and
through-hole plating, this board will provide years of trouble free life.
Resistors
Step 1 – Gather all components together. Separate the components by type (resistors,
capacitors, header, jumper, and wire). Install resistors first. Resistors have no polarity and can
be installed in either direction.
Step 2 – Install a 820 ohms / ½ watt resistor (gray, red, brown, gold) in R9 position.
Step 3 – Install 68K (68000) ohms / ½ watt resistor (blue, gray, orange, gold) in positions R1,
R2, R4, and R5.
Step 4 – Install a 100K (100,000) ohms / ½ watt resistor (brown, black, yellow, gold) in
positions R8, R7, and R10.

CAUTION
Once soldered, be sure to clip all component leads close to the circuit board. If the leads are
too long, they risk shorting or arching against the chassis when the PCB is installed.
