Install a 10K-ohm resistor (brown-black-orange) at location R10.

Solder.

Install a 10K-ohm resistor (brown-black-orange) at location R11.

Solder.

Install a 10K-ohm resistor (brown-black-orange) at location R12.

Solder.

Install a 10K-ohm resistor (brown-black-orange) at location R13.

Solder.

Carefully review your work. Make sure that locations R4 through R13 each
contain a 10K-ohm resistor. Examine all of the solder connections. Look for
unwanted solder bridges or poorly made solder connections.

Select ten 1K-ohm (1000 ohm) resistors (brown-black-red). These resistors will
be installed at locations R14 through R23 on the PC board.

Note:

save a few of the clipped resistor leads for later use as jumper

wires.

Install a 1K-ohm resistor (brown-black-red) at location R14. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R15. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R16. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R17. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R18. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R19. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R20. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R21. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R22. Solder.

Install a 1K-ohm resistor (brown-black-red) at location R23. Solder.

Select two of the discarded resistor lead clippings. Form both leads

to make jumper wires having a .3" span.
