Page 3: Populating The Circuit Board
Populating the Circuit Board Step1: Add the first 3 resistors. Use the 20k, 20k, 47k for 250 specs or use the 1M, 1M, 4.7k for Dist+ specs. Resistors are not polarized so they can go in either direction. Step 2: Add the rest of the common resistors. - Page 4 Step 3: Add the diodes. For 250 specs add the two 1N914(small orange with black stripe)with the jumper. For Dist+ specs add the two 1N34A (clear glass germanium)with the jumper. You can experiment with your own asymmetrical clipping by using one of the extra diodes in place of the jumper.
- Page 5 Step 5: Add the first two caps or omitt them. If you are building to 250 specs, do not add these caps. If you are building to Dist+ specs, then add them. Film and ceramic disc capacitors are not polarized so they can go in either direction. Step 6: Add the rest of the common caps.
- Page 6 Step 7: Add the aluminum electrolytic caps. Use the 10uf for 250 specs or use the 1uf for Dist+ specs. Aluminum electrolytic capacitors are polarized. The longer lead will be the positive and should go in the square solder pad. The sorter lead will be negative. It will have markings running down the side of the cap.
- Page 7 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.

- Page 9 Installing the LED and Mounting the Circuit Board 1. Insert the LED into its slot on the underside or solder side of the circuit board,but DO NOT SOLDER it yet. Make sure the anode(the long leg) goes in the round solder pad and the cathode(the short leg)goes in the square solder 2.
- Page 10 5. Insert the LED bulb into the LED hole in the enclosure. 6. Secure the Standoffs to the back of the potentiometers. 7. Your LED should still be free to move up and down slightly. You probably do not want your LED sticking all the way out of the hole. So pull up on the LED legs till you have it properly positioned and then solder.

Finishing Touches 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. If you've got any problems that you can't figure out yourself, visit board.buildyourownclone.com for technical support... - Page 12 Schematic...
