Find three (3) 470 ohm resistors (yellow-violet-brown).
! ! 4. Install a 470 ohm resistor at R5 and solder.
! ! 5. Install a 470 ohm resistor at R9 and solder.
! ! 6. Install a 470 ohm resistor at R11 and solder.
! ! 7. Locate a 1K resistor (brown-black-red). Install at R10 and solder.
Find three (3) 10K resistors (brown-black-orange).
! ! 8. Install a 10K resistor at R1 and solder.
! ! 9. Install a 10K at R2 and solder.
! ! 10. Install a 10K at R3 and solder.
! ! 11. Find a 47K resistor (yellow-violet-orange). Install at R6 and solder.
This completes installation of the 11 fixed-value resistors supplied with the kit.
Take a moment to inspect your solder connections and to confirm each resistor
has been installed in the right PC board location. Next, you'll install the kit's 11
disc ceramic capacitors. Note that all but one has a value of .01 uF.
Phase 2: Ceramic and Electrolytic Capacitors
Locate ten (10) .01 uF disc ceramic capacitors (marked 103).
! ! 1. Install a .01 uF disc ceramic at C1 and solder.
! ! 2. Install a .01 uF disc ceramic at C3 and solder.
! ! 3. Install a .01 uF disc ceramic at C9 and solder.
! ! 4. Install a .01 uF disc ceramic at C10 and solder.
! ! 5. Install a .01 uF disc ceramic at C11 and solder.
! ! 6. Install a .01 uF disc ceramic at C12 and solder.
! ! 7. Install a .01 uF disc ceramic at C15 and solder.
! ! 8. Install a .01 uF disc ceramic at C17 and solder.
! ! 9. Install a .01 uF disc ceramic at C18 and solder.
! ! 10. Install a .01 uF disc ceramic at C21 and solder.
! ! 11. Find the single .1 uF disc ceramic (104). Install this at C2 and solder.
Your kit also contains one electrolytic capacitor. Electrolytic caps are polarized
and must be installed the correct way in order to work. The capacitor's plus (+)
mounting hole is noted on both the circuit board and parts placement diagram. If
