ASSEMBLY OF THE MX-5
Now we are getting to the good stuff-assembling the MX-5. We will begin by
mounting first the low parts, beginning with the parts on the side of the board
without the traces. When we are finished with that side, we will begin to install
parts on the trace side of the board. This side is where all of the controls go,
and will be the side of the board facing the top of the case.
ˆ 1. Install R1, a 10K ohm resistor (brown-black-orange).
ˆ 2. Install R9, another 10K ohm resistor (brown-black-orange).
ˆ 3. Install R2, a 10K ohm resistor (brown-black-orange).
ˆ 4. Install R11, another 10K ohm resistor (brown-black-orange).
ˆ 5. Install R25, a 1K ohm resistor (brown-black-red).
ˆ 6. Install R4, a 33K ohm resistor (orange-orange-orange).
ˆ 7. Install R10, a 10K ohm resistor (brown-black-orange).
ˆ
8. Install R12 a 10K ohm resistor (brown-black-orange).
ˆ 9. Install R22, a 1K ohm resistor (brown-black-red).
ˆ 10. Install R16, a 10K ohm resistor (brown-black-orange).
ˆ 11. Install R14, a 1K ohm resistor (brown-black-red).
ˆ 12. Install D1, a 1N4148 type small signal diode (orange glass body with
black stripe on one end). Notice the direction of the diode. Make sure the
end with the line on it (cathode) is pointing in the same direction as shown
in the parts layout diagram.
ˆ 13. Install D2, the other 1N4148 type small signal diode (orange glass
body with black stripe on one end). Again make sure the striped end is
pointing in the correct direction.
ˆ 14. Install R24, a 1K ohm resistor (brown-black-red).
ˆ
15. Install R23, a 220K ohm resistor (red-red-yellow).
ˆ 16. Install R21, a 22K ohm resistor (red-red-orange).
ˆ 17. Install R18, a 10K ohm resistor (brown-black-orange).
ˆ 18. Install R7, a 33K ohm resistor (orange-orange-orange).
ˆ 19. Install R26, a 1K ohm resistor (brown-black-red).
