12. Install R10, 10K ohm (brown-black-orange).
13. Install L2, 2.2 uh inductor (green body marked with two red bands).
Modulator Section
14. Install C1, 100uf electrolytic capacitor. Electrolytic capacitors are
polarized devices with a plus (+) and a minus (-) lead. This means that
you must install them on your PC board in the correct direction, with the
plus lead going into the plus hole and the minus lead going into the
minus hole. Ordinarily, only the minus side is marked on the capacitor
body with a dark band and a clearly labeled (-) sign shown, with the
other lead being the plus (+) side. Note that the PC board layout diagram
shows where the plus side should go.
15. Install C15, .001 uf disc capacitor (marked .001, 102 or 1nf).
16. Install R1, 1K ohm (brown-black-red).
17. Install C6, .001 uf disc capacitor (marked .001, 102 or 1nf).
18. Install Q1 and Q2, 2N3904 transistors. Pay attention to correct placement
of their flat sides.
19. Install R8, 4.7K ohm (yellow-violet-red).
20. Install C5, .001 uf (marked .001, 102 or 1nf).
21. Install R9, 10K ohm (brown-black-orange).
22. Install L3, 2.2 uh inductor (green body marked with two red bands).
23. Install R7, the 1 K ohm trimmer pot. This is the small yellow device with
a screwdriver adjustment slot, marked 102. Be sure not to mix it up
with R7, the 5K pot (marked 502). Make sure it is firmly seated and
securely soldered to the PC board.
24. Install R3, the 5 K ohm trimmer pot. This is the other small yellow
device with an adjustment slot, however this one is marked 502. Make
sure it is firmly seated and securely soldered to the PC board.
25. Install D1, 1N4148 or 1N914 diode. Pay close attention to the proper
orientation of the banded end of the diode.
26. Install R6, 75 ohm (violet-green-black).
