flow in the hole such that on the top (component) side, a small amount is on the top
pad as well
There are many 1% resistors in this kit. They have light blue body color, and
sometimes the color bands are difficult to read. When in doubt, use a DVM to
measure the value. NO guessing!
The rule of soldering: don’t use too much, you can always add more! Cut the leads
flush with the top of the solder joint with your diagonal cutters.
Locate the 10K resistors (5pcs). Solder the resistors into R1 (by VR3), R6 (left of U3),
R8 (above VR3), R14 (above R8) and R19 (right of C10).
Locate the 47K5 1% resistors (4) and solder into R12 and R13 (left of U4), R20
(above R19), and R23 (top edge of pcb by C5).
Locate the 820 ohm resistors (3) and solder into R3 (left of U1), R7 (between VR2
and VR3), and R22 (by J2).
Locate the 332K 1% resistors (2) and solder R2 (above C1), and R24 (by VR1).
Locate the 68K resistors (2) and solder into R4 and R5 (above VR3).
Locate the 180K resistors (2) and solder into R9 and R10 (beside VR2).
Locate the 715K 1% resistors (2) and solder into R15 (left of U4) and R21 (right of
U4).
Locate the 620K resistor and solder into R11 (between R20/R21).
Locate the 100K 1% resistor and solder into R16 (left of VR3).
Locate the 82K5 1% resistor and solder into R17 (above R16).
Locate the 16K5 1% resistor and solder into R18 (above R17).
PART #2: BOARD WASH #1
Verify all the resistors are in the correct position.
Verify all the resistors are flat on the board. Correct if needed. Check solder joints.
Wash the board in warm water, gently scrubbing both sides. DO NOT USE ANY
SOAP! Just water!
