reason, never use force to seat a multilayer cap into the PC board. If the
spacing isn't right, pre-form the leads to the correct spacing before installation.

Locate two (2) 15 pF multilayer capacitors (marked 15 or 150).

! ! Install a 15 pF at C17 and solder.

! ! Install a 15 pF at C18 and solder.

! ! Find a 18 pF multilayer cap (18 or 180). Install at C19 and solder.

Locate two (2) 22 pF multilayer capacitors (22 or 220).

! ! Install a 22 pF at C2 and solder.

! ! Install a 22 pF at C4 and solder.

! ! Find a 56 pF multilayer capacitor (56 or 560). Install at C20 and solder.

Locate a 100 pF multilayer capacitor (101), then find the location of C7 on the
pc board. Note that the mounting holes for C7 are wider than normal for a
multilayer cap. This is due to a pc-track running between the mounting pads
beneath. To accommodate the wider spacing, carefully spread the 100 pF cap's
leads prior to installation.

! ! Install 100 pF at C7 and solder.

Locate two (2) 470 pF multilayer capacitors (471).

! ! Install 470 pF at C15, spreading leads as described above, and solder.

! ! Install 470 pF at C16 and solder.

The last six (6) capacitors in your kit are electrolytic. Electrolytic caps are
polarized and must be installed the correct way in order to work. Each
capacitor's plus (+) mounting holes are noted on both the circuit board and parts
placement diagram. If the markings on the capacitor body are unclear, the plus
(+) lead is always the longer of the two.

Locate two (2) 1 uF electrolytic caps.

! ! Install a 1 uF at C23 and solder.

! ! Install a 1 uF at C28 and solder.

Locate two (2) 10 uF electrolytic caps.

! ! Install a 10 uF at C30 and solder.

! ! Install a 10 uF at C31 and solder.

Locate two (2) 100 uF electrolytic caps.

! ! Install 100 uF at C8 and solder.
