86. Install R36, 1k ohms (brown-black-red).
87. Install R37, 1k ohms (brown-black-red).
88. Install C41, 10uF electrolytic. Remember that polarity is still important!
89. Install C3, 10nF or 0.01uF ceramic disc capacitor (marked 103).
90. Install C30, 3300pF (marked 332).
91. Install C31, 150pF (marked 151).
92. Install R18, 20k ohms (red-black-orange).
93. Install C16, 100pF capacitor (marked 101).
94. Install R25, 47k ohms (yellow-violet-orange).
95. Install C48, 0.1uF ceramic disc capacitor (marked 104).
96. Install D11, SD101 Shottkey diode (marked SD101A). Follow the
band on the PC board and the band on the diode for orientation.
97. Install R9, 270 ohms (red-violet-brown).
98. Install D3, 1N4148 small signal switching diode. This part has a
banded end that must be lined up with the band on the silkscreen and
Parts Layout Diagram.
99. Install SP1, the mini speaker. You’ll see a “+” sign on one side of the
part and the same “+” sign on the board. Line these two up and solder the
part.
100. Install R31, 3.3k ohms (orange-orange-red).
101. Install Q4, a J177 P-Channel JFET in a TO-92 package. Notice the
flat side on the part and the flat side shown on the PC board. Line the part
up with the flat side and bend the center lead out so that the part fits in the
board correctly. Push it down but not to the point of stressing the leads,
then solder all three leads in place.
102. Install a wire jumper in the spot designated for D2. Simply bend a
scrap component lead into the shape of a staple and solder it where the
board is marked for D2. Nope, there’s no polarity with a piece of wire! This
part was replaced by a jumper to improve the operation of your FM30.
103. Install another wire jumper in the D6 position. Just like D2 before,
this part was removed and we need to put a jumper in its place.
104. Install R10, 1k ohms, (brown-black-red).
