•
033. Locate resistor R12. This is 1.82M resistor (brown-gray-red-yellow).
Carefully bend the leads close to the resistor body as in Step #1.
•
034. Insert R12 into its mounting holes so the resistor body rests against
the board. Solder in place and trim the leads.
•
035. Locate resistor R16. This is 1.82M resistor (brown-gray-red-yellow).
Carefully bend the leads close to the resistor body as in Step # 1.
•
036. Insert R16 into its mounting holes so the resistor body rests against
the board. Solder in place and trim the leads.
•
037. Locate resistor R17. This is 2.7 ohm resistor (red-violet-gold).
Carefully bend the leads close to the resistor body as in Step #1.
•
038. Insert R17 into its mounting holes so the resistor body rests against
the board. Solder in place and trim the leads.
•
039. Locate resistor R19. This is 5.6 ohm resistor (green-blue-gold).
Carefully bend the leads close to the resistor body as in Step # 1.
•
040. Insert R19 into its mounting holes so the resistor body rests against
the board. Solder in place and trim the leads.
Now that you have finished Phase 1, you may want to take a few minutes to
double check your work. There are two phases to go and quite a few additional
parts to be installed; making the board more crowded and hard to find the
different components.
Now that you have finished your double check it is time to move on.
Phase 2:
Important Note: Capacitors C12-C19 are made of a polystyrene type material.
Avoid overheating these components when soldering to prevent melting the
capacitor body.
0 0 1. Locate capacitor C12 (1000pF). The is a polystyrene capacitor and
will be marked with a "1000J" on the body. (actual value in pF).
0 0 2. Mount C12 and solder both leads in place, making sure the capacitor
remains seated. Remove exc ess leads on the bottom side of the board
with diagonal cutters.
0 0 3. Locate capacitor C13 (1000pF). The is a polystyrene capacitor and
will be marked with a "1000J" on the body. (actual value in pF).
