You will begin assembly by installing the ¼-watt fixed resistors. Because these
are all 5-percent tolerance ending with a fourth gold color band, you need only
read the first three bands of the color code during the following steps. All
resistor leads should be formed as shown below.

Note: The fourth resistor color band is for tolerance, and is not called out in the
following steps.
Begin by finding the six 1.5-ohm resistors (brown-green-gold-gold). Install and
solder at the following locations:
! ! 1. R16 1.5-ohm resistor (brown-green-gold)
! ! 2. R22 1.5-ohm resistor (brown-green-gold)
! ! 3. R23 1.5-ohm resistor (brown-green-gold)
! ! 4. R24 1.5-ohm resistor (brown-green-gold)
! ! 5. R25 1.5-ohm resistor (brown-green-gold)
! ! 6. R26 1.5-ohm resistor (brown-green-gold)
! ! 7. Locate the 220-ohm resistor (red-red-brown). Install and solder at
location R1.
Locate the three 1,000-ohm (1K-ohm) resistors (brown-black-red). Install and
solder at the following locations:
! ! 8. R3 1K-ohm (brown-black-red)
! ! 9. R12 1K-ohm (brown-black-red)
! ! 10. R17 1K-ohm (brown-black-red)
! ! 11. Locate the 27,000-ohm (27K-ohm) resistor (red-violet-orange). Install
and solder at location R5.
Locate the eleven 47,000 ohm (47K-ohm) resistors (yellow-violet-orange).
Install and solder at the following locations:
! ! 12. R2 47K-ohm (yellow-violet-orange)
! ! 13. R4 47K-ohm (yellow-violet-orange)
! ! 14. R6 47K-ohm (yellow-violet-orange)
