22. Locate capacitor C5 (.1uF). This is a disc ceramic type
capacitor and will be marked "104" or "104Z" (actual value in
uF). Carefully install C5, be sure not to chip the ceramic
material. Once installed, then solder in place and trim the leads.
23. Locate capacitor C8 (.01uF). This is a disc ceramic type
capacitor and will be marked "103" or "103Z" (actual value in
uF). Carefully install C8, be sure not to chip the ceramic
material. Once installed, then solder in place and trim the leads.
24. Locate diode D1 (CDHS270). This is a Schottky diode similar to
the 1N34 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.
Remember diodes are polarity sensitive devices that must be installed
correctly. Always look for the banded or cathode end when installing, and
follow instructions carefully.
25. Insert D1 into its 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.
26. 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.
27. Insert D2 into its 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:
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.
2. Locate capacitor C11 (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 C11. Once
installed, then solder in place and trim the excess leads.
3. Locate (1) 14 pin IC socket.
4. Install the IC socket at the U1 location on the circuit board. Be
careful to orient the socket correctly according to the "Parts
