The proto board comes with the LM358 op-amp already installed.
First install the jumpers as
You will be using bare tinned copper wire for the jumpers.
The jumpers on the illustration are shown in color to indicate their function:
RED indicates positive 9 volt power jumpers.
GREEN indicates negative 9 volt power and ground jumpers.
YELLOW indicates signal level jumpers.
Next install the resistors as
Resistors R1 and R3 are installed vertically.
Resistors R2 and R4 are installed horizontally.
Next install the capacitors as
Capacitor C7 is a polarized electrolytic capacitor and must be installed with the negative lead in Row 11.
The completed proto board:;
Here's the schematic diagram for the crystal set.
