47. Install C9, .01uF capacitor
48. Install C10, .01uF capacitor
49. Install C14, .01uF capacitor
50. Install C15, .01uF capacitor
51. Install C16, .01uF capacitor
52. Install C17, .01uF capacitor
Remember that 3.9M ohm resistor, marked 395, we didn't install? Well, it's
R33 and now is the time to install it.
53 R33 is installed a little differently. We're going to install it right on top
of C2 that you installed in step 40. Relax, you're an expert SMT compo-
nent installer now and it's not that hard. Simply place R33 on top of C2
and flow a little solder up from the connection on C2 next to D4 up to R33.
Then do the same for the other connection next to D3.
Find the 8.2pF capacitor package
54. Install C12, 8.2pF capacitor
Now for the 220pF capacitor
55. Install C4, 220pF capacitor
Ok, now you need to be careful and pay attention to the instructions. Locate
the 10uF electrolytic capacitor, marked 10.
56. Install C3, 10uF capacitor. This capacitor is a little silver cylinder with
a black base. You will notice that there is a black mark indicating the "-"
terminal on one side of the cylinder and the 2 corners of the base are
notched at a 45 degree angle indicating the "+" terminal. C3 MUST be
positioned so the black mark is to the left and the notches are on the right.
There are two small leads on the bottom of the capacitor which must be
placed over the two solder pads on the board. Apply a little solder on
each of the board pads and then place C3 over the pads and apply heat
to one of the pads, not the capacitor lead, at a time being careful to not
get the black plastic base too hot. This will melt the pad solder first and
allow it to flow onto the capacitor pad. Check the alignment and then sol-
der the other connection.
REMEMBER!! DO NOT clean the circuit board!!!
