2.4 Install all the ceramic capacitors
Install all 16 through-hole capacitors in accordance with the following diagram. The procedure is
so easy that I have included all capacitors in a single assembly step rather than doing one
diagram for each capacitor value. Nevertheless be very careful to insert the correct value
capacitors in the correct places. Mistakes are hard to correct later.
In the diagram, the component label (capacitor body inscription) is written inside the capacitor
body which is coloured yellow. The actual value e.g. 220pF is written in red text next to the
capacitor. Note that the leads of the 56pF capacitor (“56J”) need to be bent to fit the 2.5mm holes.
