STEP 50
Solder the components
on the eyelet board
The components and jumpers are on
the board, and double-checked for
correct placement and tight wraps .
It’s time set the connections with
solder .
Review the tips for great soldering on
page 19, then solder each connection
on the eyelet board, except for one:
don’t solder eyelet 16 yet .
Trim the two leads connected to
eyelet 16 (the 10K metal oxide resistor
and the 16μF filter cap) . Trimming
these leads is important to avoid a
short in your power supply . Don’t
solder eyelet 16 yet . Wait until you’ve
installed the eyelet board to the chas-
sis, because you’ll be adding the red
wire from the output transformer to
this eyelet .
After all the joints are soldered, clip
the excess leads on both the back and
the front of the board .
Check all your solder joints to make
sure they’re shiny, and to make sure
you didn’t miss one .

STEP 51
Install the eyelet board, backed
by the insulator board
Before installing the eyelet board and
insulator board in the chassis, make
sure you have enough length on the
unsoldered jumpers coming through
holes 1, 15, 4 and 23 to reach their
components .
Hole 1: 2-1/2"
Hole 15: 3-1/2"
Hole 4: 2-1/4"
Hole 23: 2"
Lay the insulation board on the bot-
tom of the chassis, aligning it with the
mounting holes .
Run a 6-32 x 1/2" machine screw
through the eyelet board, the insula-
tion board and through the chassis .
Secure it with a lock nut on the out-
side of the chassis . Do the same with
the second machine screw .
