- 1). Place the circuit board on your work surface with the numbered side facing up. The numbers on the side are read like the headings on a graph. To locate a wire position (like A2), find the A on one edge, and then find the 2 on the other edge and find the hole that the two lines share. The wire goes in that hole. Keep this in mind as you locate the slots to connect your wires. Insert your first jumper wire connecting J22 to I27.
- 2). Separate your resistors. The resistor that has brown, black and orange stripes is your 10,000 ohm-resistor. The ones with a brown, black and yellow stripe are your 100,000-ohm resistors. A green, black and black stripe is a 50-ohm resistor.
- 3). Put the jumper wires of the brown, black and orange striped resistor through G20 to F28 on your circuit board. Take one of the brown, black and yellow striped resistors and connect H27 to H28. Use the remaining brown, black and yellow resistor to connect I28 to I29. Now place the last resistor, the 50-ohm (green, black, black), to connect I33 to I34.
- 4). Your MPSW45A transistor should be placed to connect J27, J28, and J29 on the circuit board.
- 5). Insert the speaker wires so they connect F29 and J33.
- 6). To power your amplified circuit board, take the 9-volt battery cap (which should have one red and one black wire extending from it) and connect the black wire to F26 and the red wire to F34. Place the cap on your 9-volt battery and you are ready to connect your amplified speaker board. Your input wires connect to the first jumper wire you installed on your board.
