• 026. Locate diode D2 (1N34). This is a germanium diode and is made from
a clear glass type material. This part will have a band on one end
indicating the cathode end of the diode.
• 027. Insert D2 into it s mounting holes so the diode body rests against the
board. Be sure to observe the circuit marking indicating the cathode.
Solder in place and trim the leads.
Now that you have finished Phase 2, you may want to take a few minutes to
double check your work. There is still one more phase to go.
Now that you have finished your double check it is time to move on.
Phase 3:
• 0 1. Locate capacitor C10 (10uF). This is an electrolytic type capacitor and will
be marked "10uF" (actual value in uF). Carefully install C10, be sure
to orient the negative end of the capacitor properly. Please refer to
the section titled, "Parts Placement", Figure 1 for correct orientation
of C10. Once installed, then solder in place and trim the excess leads.
• 0 2. Locate capacitor C l 1 (10uF). This is an electrolytic type capacitor and
will be marked "10uF" (actual value in uF). Carefully install C11, be
sure to orient the negative end of the capacitor properly. Please refer
to the section titled, "Parts Placement", Figure 1 for correct
orientation of C 11. Once installed, then solder in place and trim the
excess leads.
•
0 3. Locate (1) 14 pin 1C socket.
• 0 4. Install the 1C socket at the U1 location on the circuit board. Be
careful to orient the socket correctly according to the "Parts Placement"
section Figure 1.
• 0 5. Carefully bend over the four corner pins of the socket against the
solder pads on the solder side of the board. Solder in place.
•
0 6. Locate another 14 pin IC socket.
• 0 7. Install the IC socket at the U2 location on the circuit board. Be
careful to orient the socket correctly according to the "Parts Placement"
section Figure 1.
• 0 8. Carefully bend over the four corner pins of the socket against the
solder pads on the solder side of the board. Solder in place.
•
0 9. Locate the remaining 14 pin 1C socket.
