lead is not only shorter than the other, it has a band or stripe running
down the body of the part next to the short lead that shows zeros or minus
signs. Be sure to install the part so that the positive lead goes into the
hole marked with a “+” sign and the negative lead into the other. Push the
part down until it sits on the board and solder both leads.
Install C15, 10nF ceramic disc capacitor (marked 103).
Install C6, 220nF ceramic disc capacitor (marked 224).
Install C20, 390nF ceramic disc capacitor (marked 394).
Install C8, 220nF ceramic disc capacitor (marked 224).
Install C16, 10uF electrolytic capacitor. Remember to orient the part
following the “+” sign on the silkscreen and Parts Layout Diagram.
Install R8, 47k ohms (yellow-violet-orange).
Install C3, 10nF ceramic disc capacitor (marked 103).
Install C26, 220nF ceramic disc capacitor (marked 224).
Install C17, 10uF electrolytic capacitor. Remember the polarity when
installing.
Install C7, 220nF ceramic disc capacitor (marked 224).
Install C19, 390nF ceramic disc capacitor (marked 394).
Install C18, 10uF electrolytic capacitor. Watch orientation!
Ok, if you haven’t already done so you might consider a little break at this
point. Rest your eyes, stretch, then take a look at your parts placement and
solder joints to be sure they look great before moving on.
Install C21, 10nF ceramic disc capacitor (marked 103).
Install R13, 47k ohm resistor (yellow-violet-orange).
Install C25, 10nF ceramic disc capacitor (marked 103).
Install C30, 10uF electrolytic capacitor. I’d remind you to be careful how
you install the part, remembering to check the polarity before soldering,
but I don’t want to bug you about it.
Install C13, the last 10nF ceramic disc capacitor (marked 103).
Install C10, 10uF electrolytic capacitor. Polarity.
Install C11, 100pF ceramic disc capacitor (marked 100, 100K, or 101).
