- Page 2 PARTS CHECKLIST (BA6110 Version) RESISTORS: Some kits may come with 1%metal film (light blue) or 5%carbon film(light brown) 1 - 100ohm (brown/black/black/black/brown) or (brown/black/brown/gold) 3 - 1k (brown/black/black/brown/brown) or (brown/black/red/gold) 1 - 2.7k (red/purple/black/brown/brown) or (red/purple/red/gold) 4 - 4.7k (yellow/purple/black/brown/brown) or (yellow/purple/red/gold 1 - 6.8k (blue/gray/black/brown/brown) or (blue/gray/red/gold)
- Page 3 POTENTIOMETERS: 1 - 10k trimpot 1 - 500k trimpot 1 - B50k (depth) 1 - A250k (rise time) 1 - C250k (rate) SWITCHES: 1 - 3PDT footswitch 1 - SPST momentary footswitch 1 SPDT toggle switch MISC.: 4 - DIP8 sockets 1 - SIP9 socket 1 - predrilled enclosure w/ screws 1 - ready to solder circuit board...
- Page 4 Populating the circuit board Step1: install all the diodes. Make sure the black stripe is facing the same direction as the stripe on the layout.
- Page 5 Step 2: Install all the resistors. Resistors are non-polarized so it makes no difference which direction your orientate them. There is a lot of soldering here so take your time. Do it one at a time if you have to. Save some of the clippings from the excess leads. You will need them later on.
- Page 6 Step 4: install the trimpots. They will only have 3 legs, but the board has 5 holes. This is so that the board can accomodate more than one brand of trimpot. There should only be one way to fit your trimpot into the space provided without having to bend the legs very much. You may have to bend them a little bit if they were bent in shipping, but you should not have to stretch the legs to get it to fit.
- Page 7 Step 8: Install the aluminum electrolytic capacitors. This are polarized and should be orientated a certain way. The positive end will have the longer lead and should go in the hole with the square solder pad. The negative end will have the shorter lead and have a stripe going down the side of the cap.
- Page 8 Step 10: Install the ceramic disc caps. These are not polarized and can go in either direction. They are the small orange lolipop caps. Step 11: install the film caps. These are not polarized and can go in either direction.
- Page 9 Step12: DO NOT SOLDER the BA6110!!!! Only solder the SIP9 socket. And make sure you solder it to the UNDERSIDE of the board. Install the Chip into the socket when you are ready to test the pedal.(this is a pic of the 622 board, but the layouts are virtually identical) DO NOT DO STEP 13 IF YOU HAVE A RECENT KIT!!!!!!!!!!!This jumper is needed on the first run of PCBs to compensate for a very minor error.
- Page 10 Step 14: Add the 1/4 jacks. Both are stereo, so it makes no difference which is in or out . MAKE SURE YOU SOLDER THEM TO THE UNDERSIDE OF THE BOARD!!!! Step 15: DO NOT SOLDER!!!!!!!!!!!!!!!!!!!!!!Only insert the LED into it's place on the underside of the circuit board but do not solder it.
- Page 11 Assembly 1. Install the SPDT toggle switch VERY IMPORTANT!!!! Take off the extra nut and washer from the inside of the brushing so that there is only one nut and one washer (the serated washer) on the outside of the enclosure on the body of the switch is flush against the inside of the enclosure.
- Page 12 Wiring 1. Make these wiring connections on underneath the board. Also keep in mind that these wires should be very short. They are shown here as being relatively long for illustration...
- Page 13 purposes. 2. Look at the yellow wire. This is the chassis ground wire . Because all of the jacks are plastic, the circuit ground is isolated from the chassis. This can cause some grounding noise when you press the metal footswitches. Connecting the circuit ground to the chassis will eliminate this.
- Page 14 Finishing Up 1. Test the pedal to make sure it works properly before you solder the LED. 2. Add all the IC's to their sockets. The DIP8 ICs may have a u-shaped notch. If they do, match them up with the notch in the socket that should also be matched up with the layout. If there is no notch, then there should be a small dot in the corner of the IC that denotes pin 1.
