25. Install R19, 470 ohms (yellow-violet-brown).
26. Install R27, 15k ohms (brown-green-orange).
27. Install C23, 10nF (marked 103).
28. Install C22, 0.1uF capacitor (marked 104).
29. Install R22, the last 15k ohm resistor (brown-green-orange).
30. Install R18, 10k ohms (brown-black-orange).
31. Install R16, 10k ohms (brown-black-orange).
32. Install R7, 4.7k ohms (yellow-violet-red).
33. Install R8, also 4.7k ohms (yellow-violet-red).
34. Install R11, 4.7k ohms (yellow-violet-red).
35. Install R10, another 4.7k ohm resistor (yellow-violet-red).
36. Install R24, 4.7k ohms (guess the color code or look above!!)
37. Install R23, yet another 4.7k ohm resistor (yellow-violet-red).
38. Install C26, the first of the 1uF electrolytics. Don’t confuse these with
the 10uF parts you’ve been installing; they’re marked 1uF right on the side
of the capacitor. They are polarity sensitive just like the others though, so
follow the silkscreen for orientation of the positive lead.
39. Install C29, another 1uF electrolytic capacitor. Polarity!
40. Install C28 and C27, 10uF electrolytics. Again, be sure they’re marked
as 10uF and watch the orientation when installing.
41. Install C25, 1uF electrolytic capacitor. Bet you can guess that I’m
going to tell you to be sure you orient it correctly before soldering! But hey,
being reminded beats a big popping sound when you fire up your kit and a
cap explodes, doesn’t it?
42. Install C5, the honkin’ huge orange capacitor marked .1M and also
1KV. This part can be installed in either direction but please be sure you
seat it down on the board as far as you can without damaging it. If you
don’t then you’ll have trouble getting the top cover on, you’ll call me, and
I’ll say “I told you so”. Let’s avoid all that and get it down on the board
right away, then solder both leads. There are several holes all around this
part so be sure you get the right ones;they are the two larger center holes
within the silkscreen outline of the part.
43. Install C4, one of the large red 0.01uF capacitors (marked .01M).
44. Install C3, the other large red 0.01uF caps (marked .01M).
45. Install R30, a 5.6k ohm resistor (green-blue-red).
