IO_Board:
Here is the part list:
Make it:
![]() | Here is the IO_Board |
![]() | Solder all resistors. Solder each value one after the other. |
![]() | Solder D9 diode 1N4148 MAKE SURE DIODE IS IN THE RIGHT WAY |
![]() | Solder the electrolytic capacitor MAKE SURE ELECTROLYTIC CAPACITOR IS IN THE RIGHT WAY
|
![]() | Assemble the two 2SA733 transistors they are the output buffers of TRIG1 and TRIG2
MAKE SURE TRANSISTORS ARE IN THE RIGHT WAY |
![]() | Solder the 14 6.35mm Jacks |
![]() | Solder the four Din connectors |
![]() | Solder the 6N138 optocoupler |
![]() | Solder the three cable 4 wires and the cable 10-wire on IO_Board. |
![]() | Strip one end of the audio cable and connect both ground together as a on the picutre. Tin your cable. |
![]() | Strip the other side and cutting both ground.Tin it. |
![]() | Solder the end of the cable who has three wires (red, white and ground) to IO_Board. Take the red wire to No. 1, the ground in the middle and white for the No. 3 as the picture. |
![]() | Now solder the cables 4-wires and 10-wires to the Main_Board. This is a bit tricky. Be careful. |
![]() | Now solder the other end of the audio cable to the Main_Board in the master section. Take the red wire as No. 1 and No. 3 for white. There is nothing to solder on the pad in the middle. |
![]() | Desoldering and make power cables shorter with a length of 8cm. |
![]() | Resolder the power supply cables. RESPECT THE ORDER OF WIRING. LOOK WELL THE PICTURE. THE PADS ARE FACING EACH OTHER! You can then go to Finished assembly |
