30. Locate resistor R4. This is a 130K resistor (brown-orange-yellow).
Carefully bend the leads close to the resistor body as in Step #1. Insert
at R4, solder in place and trim the leads.
! !
31. Locate resistor R16. This is a 240K resistor (red-yellow-yellow).
Carefully bend the leads close to the resistor body as in Step #1. Insert
at R16, solder in place and trim the leads.
! !
32. Locate resistor R32. This is a 5.1 ohm, 1/2 watt resistor (green-
brown-gold). Carefully bend the leads close to the resistor body as in
Step #1. Insert at R32, solder in place and trim the leads.

33. Locate resistor R36. This is a 68 ohm, 1/2 watt resistor (blue-gray-
black). Carefully bend the leads close to the resistor body as in Step
#1. Insert at R36, solder in place and trim the leads.
Installing Non-polarized Capacitors:
Important Note: Capacitors C5-C8 are made of a polystyrene type material.
Avoid overheating these components when soldering to prevent melting the
capacitor body.
! !
1. Locate capacitor C5 (1000pF). The is a polystyrene capacitor and will
be marked with a "1000J" on the body (actual value in pF).
! !
2. Mount C5 and solder both leads in place, making sure the capacitor
remains seated. Remove excess leads on the bottom side of the board
with diagonal cutters.
! !
3. Locate capacitor C6 (1000pF). The is a polystyrene capacitor and will
be marked with a "1000J" on the body (actual value in pF). Insert at
C6, solder in place and trim the leads.
! !
4. Locate capacitor C7 (1000pF). Insert at C7, solder in place and trim
the leads.
! !
5. Locate capacitor C8 (1000pF). Insert at C8, solder in place and trim
the leads.
! !
6. Locate capacitor C1 (.1uF). The is a disc ceramic capacitor and will
be marked with either a "104" or "104Z" on the body (actual value in
uF). Insert at C1, solder in place and trim the leads.
! !
7. Locate capacitor C3 (.1uF). Insert at C3, solder in place and trim the
leads.
! !
8. Locate capacitor C16 (.1uF). Insert at C16, solder in place and trim
the leads.
