BYOC Envelope Filter Kit Instructions
These are the instructions for the newer bezel free
version. If you have an older kit with a bezel, there
really isn't much difference. You could use these
instructions without much trouble, but you should

Page 2: Populating The Circuit Board
VTL5C4/2 Potentiometers: 2 - A100k log Hardware: 1 - enclosure w/ 4 screws 1 - byoc envelope filter kit circuit board 1 - 3pdt footswitch 2 - knobs 1 - AC adaptor jack 1 - ¼ stereo jack 1 - ¼ mono jack... - Page 3 Step 1: Add the diodes. Make sure the black stripes are facing the same way as show on the layout. Step2: Add the resistors. Resistors are non-polarized, so you can put them in either way. The 820k is the sweep resistor. Increasing this resistor will increase the range of the sweep.
- Page 4 Step3: Add the Op Amp. Pin 1 of the op amp will go in the square solder pad. Pin 1 is sometimes denoted by a small dot on the top of the chip. Sometimes there will also be a U-shaped notch in one end. Match this notch up with the notch in the layout. Sometimes there is only one or the other, but if there are both markers, always defer to the U-shaped notch first.
- Page 5 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.
- Page 6 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 8 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 9 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. 8.

Page 10: Finishing Touches
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. That's it. You're done. If you've got any problems that you can't figure out yourself, visit board.buildyourownclone.com technical support.
