three leads.
56. Install C48, 35 pF trimmer capacitor (round red part with adjustment).
This part can be installed either way.
57. Install C54, 62 pF ceramic capacitor (marked 62).
58. Install R18, 22K ohm standup resistor (red-red-orange). The
silkscreen for this part is hard to see but you know it’s in the area; use the
Layout Diagram to locate it if you need to.
59. Install C22, 1nF disc capacitor (marked .001 or 102).
60. Install C39, another 1nF disc capacitor (marked .001 or 102).
61. Install C16, 0.01 µF disc capacitor (marked .01 or 103 or 10nf).
62. Install R9, 470 ohm standup resistor (yellow-violet-brown).
63. Install R28, 22 ohm resistor (red-red-black).
64. Install C46, 0.1 µF disc capacitor (marked .1 or 104).
65. Install L7, 0.18uH shielded can coil [metal body]. There is no polarity
with this part so install it as it fits and solder all 4 leads.
66. Install C51, 0.1 µF disc capacitor (marked .1 or 104).
67. Install R32, 470 ohm standup resistor (yellow-violet-brown).
68. Install R34, 47k ohm standup (yellow-violet-orange).
69. Install FL1, 10.7 Mhz filter (brown molded, 3 leads).
70. Install C56, 1nF disc capacitor (marked .001 or 102).
71. Install Q3, 2N3904 NPN transistor. Follow the PC board silkscreen
and Parts Layout Diagram for proper orientation of the flat side.
72. Install C35, 1nF disc capacitor (marked .001 or 102).
73. Install R16, 51 ohm resistor (green-brown-black).
74. Install C29, 1nF disc capacitor (marked .001 or 102).
75. Install C34, 82 pF ceramic capacitor (marked 82).
Be very careful with the red and orange color bands on resistors, and
also the violet/brown bands. The colors are different from various
manufacturers and are sometimes very close in color and easy to
confuse. If you really can’t tell, measure the resistor with an ohm-meter.
