In the steps that follow, you'll be installing groups of
components. When working from a long list, install all of the items on
one line before moving on to the next. Arrows (
⇒
) appear in the list
to remind you of this order. In general, assembly proceeds from left to
right and front to back across the board.
Install the capacitors listed below. Start with C29, which is to the
left of C55, near relay K16.
Check each capacitor's labeling
carefully (shown in parentheses).

Install the high-voltage capacitors listed below.
Note:
Save a few of the clipped leads from these capacitors for use as
ground jumpers in later steps.

Install the electrolytic capacitor, C42 (10 µF), near the back-right
corner of the board. The (+) lead must be installed in the hole marked
with a "+". The (+) lead is usually longer than the (–) lead, and the (–)
lead is identified by a black or white stripe.
Install the 5 to 30 pF ceramic trimmer capacitor, C31, near the
back edge of the board. Orient the flat side of the trimmer as indicated.
Using a small flat-blade screwdriver, set the trimmer to its
midpoint (screwdriver slot perpendicular to the flat side).
Sort all of the resistors by value. The color bands on 1% resistors
(which usually have a blue body) can be difficult to read, so you should
use a DMM (digital multimeter) to verify their values. Tape them to a
piece of paper with the values labeled.
Install the resistors below. Start with R18, which is at the front
edge of the board, near the microcontroller, U1 (the only 40-pin IC).
