Populating the Circuit Board Step 1: Add the diodes. Make sure the black stripes are facing the same way as show on the layout. Step2: Add the resistors. The 22k resistor highlighted in yellow is a typo. It should be a...

2.2k resistor. The 820k is the sweep resistor. Increasing this resistor will increase the range of the sweep. The original DOD440 had a 470k resistor. The 820k resistor will give a much fuller sweep. The kit comes with an extra 1M resistor to use here as wellfor even more range.

notch first. Step 4: Add the aluminum electrolytic caps. These are polarized. The positive end will have a longer lead and goes in the square solder pad. Step5: Add the film caps. These are not polarized and can go in either way.

Step6: Add the Opto-Coupler. It should be fairly obvious that the side with 3 leads goes in the side that has 3 solder pads and the side that has 2 leads goes in the side that has 2 solder pads. The writing on the opto-coupler should be facing up. The positive end will be marked with a and should match up with the on the layout.

Assembly 1. Install the jacks first. If you are looking down inside the enclosure, the mono jack goes on the right side and the stereo jack goes on the left. Place the washer on the outside of the enclosure. Use a 1/2" wrench to tighten. 2.

After you mount and install the LED/bezel, Bend the leads of the LED into circles so that you will have something to solder the hookup wire to. DON'T lose track of which lead is negative and positve. The positive lead will be longer. The negative side has a flat side.

Keith's tips to for a cleaner build 1. Use the left over clippings from you capacitors and resistors when ever possible. But don't use them if it may cause a short.You wouldn't want to use them to make the connection from the sw2 eyelet to lug 2 of the footswitch and for sw1 to lug 1 of the footswitch because those would overlap and probably touch.
Finishing Touches If you were holding out to bus bar wire the sleeves of the jacks don't forget to do that. Install the base of the enclosure with the 4 screws that came with your kit. Add the rubber bumper feet...unless you're a velcro person. That's it. You're done.
