  • Page 4 Now move on to the protective fuses. They look quite similar to ceramic capacitors and are placed in the blank rectangular markings on the board around the diodes. Next place and solder the sockets. Make sure that the notch is in the ​ s ame direction​ as printed on the circuit board.
  • Page 5 Next solder in the four BS170 unipolar transistors, two 2N3904 NPN transistors and two 2N3906 PNP transistors. Take care that they are oriented the same way as printed on the board. BOTTOM BOARD BACK SIDE Take the 10 pin power connector and place it also on the back side of the board. It might be tricky to solder it straight, but you can place something like your cutter under the board to hold it level.
  • Page 6 Wrong label on the board.​ The 100uF electrolytic capacitors are replaced with 10uF. Now, it’s time for more capacitors. Take the four 10uF and two 1uFcapacitors and place them on the front side of the board. Be careful, these are ​ p olarized!​ capacitors and should be soldered the​ right way​ i n. There is a + marking on the circuit board that should match the long lead of the capacitor, the –...
  • Page 7 Now to ensure that the headers are properly aligned, screw the hex screw and the standoff on bottom board. Place the female headers on button board with the male pins inserted. Now place top board, screw with the standoff screw and finally, solder the headers to both boards. Just like in the image below. Unscrew the top spacer again and disconnect the two boards.

    ENCLOSURE ASSEMBLY Again we want to make sure that all the ​ c omponents are properly aligned​ with the front panel, so take the standoff and place it in the opening. Check that all the components came through and then screw the wooden front panel with the second hex screw.
  • Page 9 The switch and the LED ​ s hould have some space​ off the board, or else they won’t come through the panel, like in the image below. Solder the LEDs, the switches and the rest of the components. Congratulations! You have made it through, now just connect the bottom board, add the knobs, the jumpers to your preferred configuration and you are ready to enjoy your new module.

  • Page 10: Troubleshooting

    Before you connect anything, make sure that your system is disconnected from power. Also double check the polarity of the ribbon cable, the red cable should match the -12V rail both on the module and on the bus board! TROUBLESHOOTING did you plug it in? RELEASES ●...
