Place the largest 10 kΩ resistor (labeled 103) in the outline labeled R4 on the board.

For a handy surface-mount resistor value calculator, click here. All the resistors in this kit are 3 digit EIA (Electronic Industries Alliance).

Re-heat the solder while holding the resistor in its outline until the molten solder envelops the end (shiny) cap.

All the resistors through Step 13 are symmetrical and can be soldered in either orientation.

If the solder won't envelop the cap, add some flux or a little fresh solder and try again.

Remove the iron, then remove the tweezers once the solder has cooled.
