This completes installation of the 16 fixed-value resistors (the three variable
resistors will be installed later). Next, we'll install the kit's 17 disc ceramic
capacitors. All capacitors should be seated as close to the board as possible.

! ! Find a 2.2 pF disc ceramic capacitor (2.2). Install at C3 and solder.

! ! Find a 4.7 pF disc ceramic capacitor (4.7). Install at C1 and solder.

! ! Find a 6.8 pF disc ceramic capacitor (6.8). Install at C5 and solder.

Locate five (5) .001 uF disc ceramic capacitors (102).

! ! Install a .001 uF at C6 and solder.

! ! Install a .001 uF at C13 and solder.

! ! Install a .001 uF at C14 and solder.

! ! Install a .001 uF at C25 and solder.

! ! Install a .001 uF at C32 and solder.

Find a .05 uF disc ceramic capacitor (503). Looking at the pc board, note that
two (2) installation holes are provided for the ground-side of C27. Choose the
one that most closely matches the lead spacing for the .05 uF capacitor provided
in your kit.

! ! Install .05 uF at C27 and solder.

Locate eight (8) .1 uF disc ceramic capacitors (104).

! ! Install .1 uF at C10 and solder.

! ! Install .1 uF at C11 and solder.

! ! Install .1 uF at C12 and solder.

! ! Install .1 uF at C21 and solder.

! ! Install .1 uF at C22 and solder.

! ! Install .1 uF at C24 and solder.

! ! Install .1 uF at C26 and solder.

! ! Install .1 uF at C29 and solder.

There are 9 multilayer capacitors provided with your kit.

A multilayer cap is similar to a surface-mount "chip" capacitor, except that it
has a lead spot-welded onto each end of the capacitor body. Multilayers have
superior radio-frequency operating characteristics, but the lead welds may fail
if the device is over-heated and stressed during installation or removal. For this
