  • Page 4: Populating The Circuit Board

    Populating the Circuit Board Step 1: Add the diodes. Make sure the black stripe (anode) is facing the correct way. Step2: Decide if you want your LED statis light to blink or stay static. Use the 470ohm for a blinking light or 4.7k for a static light. Only add one or the other. DO NOT ADD BOTH!
  • Page 5 Step 3: Add the rest of the resistors. Resistors are not polarized so you can put them in either direction. You can pull the 22k resistor to modify to vibrato. Step 4: Add the IC sockets. Do not add the actual chips themselves to the socket until the end.
  • Page 6 Step 5: Add the 100k trimpot. Step 6: Add the transistors. The 2N5088 are highlighted in red. The 2N5087 is highlighted in yellow. Be sure to orientate the transistors so that the flat sided match up with the circuit board layout. If you kit came with MPS series transistors, you should use the two MPS6521 in place of the 2N5088 and use the MPS65243 in place of the 2N5087...
  • Page 7 Step 7: Add the electrolytic caps. These are polarized. The positive lead will be the longer of the two and will go in the squar esolder pad. Step 8: Add the ceramic disc caps. These are not polarized.
  • Page 8 Step 9: Add the 2.2uf tantalum cap. This cap is polarized.Insert the positive end closer to the 47ohm resistor and the negative end closer to the 100k resistor. Sometimes this capacitor will have a longer lead on the positive end. If both the leads are the same length, then the postive end will have a ++ symbol over the postive lead.
  • Page 9 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 10 This is a disconnect ac adaptor jack. That means that when you have a battery connected and you plug in the adaptor, it will disconnect the battery. That is why there are 2 positive terminals. They are both connected when there is no plug in the jack, but when the plug is inserted only one of the terminals (the uppermost terminal in the back view ) is connected to the sleeve of the adaptor.

  • Page 12 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 13 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.
