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. Components may be soldered one at a
time or in groups. Leads can be trimmed either before or after
soldering. After trimming, leads should be 1/16" (1.5 mm) or less in
length.
Install six additional PN2222 transistors on the back side of the PCB
(the side that is not silk-screened) just as you did Q5. Align the flat side of
each transistor with the outline shown on the silk screening.

Install capacitor C1, .047
F (473) on the back side of the PCB (the
side that is not silk-screened). Position the capacitor as shown in Figure 9.

Install capacitor C4, .001
F (102) on the back side of the PCB
(the side that is not silk-screened).
Install ceramic resonator Z1 (4.0 MG or 4.00 MG) on the back
side of the PCB (the side that is not silk-screened). This part may be
inserted in either direction. Like the capacitors, insert the resonator as
far as the plastic coating on the leads will allow.
Install JP1, a two pin header connector on the back side of the
PCB (the side that is not silk-screened) as shown in Figure 10 .
Temporarily place a shorting block on the pins to provide a finger rest
while soldering. Do not hold the solder iron on the pins more than
1 or 2 seconds. Excessive heat will melt the plastic part of the
header.

Check to ensure that:
_ All of the above parts were installed in the back of the PCB
(the side with no silk-screening).
_ All parts are soldered.
_ All leads are trimmed to 1/16” (1.5 mm) or less.
