i. There are two 22pF ceramic capacitors (C9,C10). Place the 22pF capacitors in their
respective places on the PCB and bend the leads out on the back so they don’t fall
out (34,35). Once again, please make sure you install the 22pF caps in their correct
locations - don’t mix them up with the 100nF variety.

ii. There are seven 100nF ceramic capacitors (C2-C8). Like the resistors, these capacitors
are not polarized. It doesn’t matter which lead goes into which hole. Place all the 100nF
capacitors in their respective places on the PCB and bend the leads out on the back.

Electrolytic Capacitors: There is one 220uF cap (C1). Electrolytic capacitors ARE
POLARIZED: there is a right way and a wrong way to install them. If you get it wrong the
cap might burst. The white stripe on the case indicates the negative lead of the cap (38).
STRIPE = NEGATIVE = SHORT LEAD = ROUND PAD
NO STRIPE = POSITIVE = LONG LEAD = SQUARE PAD
Make sure you orient this cap properly! Notice how the long lead is directed into the square
pad (38). For reference, Figure 3 has a little red plus sign(+) on the positive pad. Bend out
the leads, flip the board over, solder and snip all the leads.
