  • Page 6: Populating The Circuit Board

    Populating the Circuit Board Step 1: Add all the resistors. Resistors are not polarized and can be inserted in either direction.
  • Page 7 Step 2: Add the diodes. Be sure to match the end of the diodes with the stripe to the layout on the PCB. The striped end should go in the square solder pad.
  • Page 8 Step 3: Add the ICs. Be sure to orient them correctly. There may be a "U" shaped notch on the IC between pins 1 and 8. Line that up with the screenprint on the PCB. If your IC does not have a notch, look for a dot to indicate pin Pin one on the PCB will be a square hole.
  • Page 9 Step 4: Add the film and ceramic disc capacitors. These are non-polarized and can go in either direction. The ceramic disc capacitor is highlighted in yellow.
  • Page 10 Step 5: Add the aluminum electrolytic capacitors. These ARE polarized, meaning there is a positive and negative end. The positive side will have a longer lead and goes in the square solder pad. The negative side will have a shorter lead and a stripe running along the body of the cap, and goes in the round solder pad.

  • Page 11: Enclosure Hardware Assembly

    Enclosure Hardware Assembly Step 1: Mount the DC adapter jack.
  • Page 12 Step 2: Mount the potentiometers. You will mount them opposite each other, so that when looking into the enclosure, the right potentiometer will have its lugs facing towards the ac jack, and the left potentiometer will have its lugs facing the audio jacks.
  • Page 13 Step 3: Mount the Audio Jacks. You want to orient them so that the SLEEVE terminals (beveled corner of the jack) are facing away from each other. If looking at the inside of the enclosure, the OUTPUT jack will have its sleeve terminal facing towards the AC jack.
  • Page 14 Step 4: Remove both nuts from the footswitch and mount the footswitch. Orient the footswitch so that the flat sides of the solder lugs are like the diagram below. NOTE: There are no actual number markings on the footswitch. There are two correct ways you can orient the footswitch.

  • Page 16: Wiring

    Wiring FLIP PCB OVER!!! STEP 1: Wire the PCB as shown in the diagram below. Make all connections to the back side of the PCB and solder on the top (screen printed) side of the PCB. Make the wires as short as possible but allow enough length so that if you need to do any trouble shooting later, you will be able to do so without having to remove all the enclosure mounted components.
  • Page 17 Step 2: Once the AC jack, potentiometers, and IN/OUT jacks are wired, insert the LED in its hole. Insert the long lead into the square hole!!! might want to slightly bend the leads away from each other to keep them in the holes for now.
  • Page 18 Step 3: Flip the PCB right-side-up, tuck the wires into the enclosure, and place the PCB onto the footswitch. DO NOT SOLDER YET!!!!! It is extremely important that when you place the PCB on the footswitch, you make sure to tuck all the wires out of the way so that that PCB can rest flush against the enclosed jacks and footswitch.
  • Page 19 Step 4: Solder ONLY 1 of the footswitch lugs. Your PCB should be recessed inside the enclosure about 1cm. It should be level. Some of your components may be sticking up out of the enclosure just a bit, particularly the film capacitors. This is to be expected. This is OK. The lid has a deep recess.
