Line 37: When you are happy with the printed circuit board, construction can proceed as normal, starting with the resistors first, followed by the IC sockets if used, then moving onto the taller components. Take particular care with the orientation of the polarized components, the electrolytics, LEDs, diodes, transistors and ICs. When inserting the ICs in their sockets, take care not to accidentally bend any of the pins under the chip. Also, make sure the notch on the chip is aligned with the notch marked on the PCB overlay. Line 44: [[File:cgs_photo_cgs13v2-2_pcb_rear.jpg\|thumb\|center\|600px\|This photo of the rear of the PCB show the positions for the surface mount decoupling capacitors.]] The LED resistors (RL) can be selected as needed. If you are using common LEDs, 1k to 2k2 would be appropriate. If you are using any of the super-bright modern LEDs for their unique colors, the resistors can be much higher, 10k to 33k for example, so that the LEDs don't dazzle you. [[File:cgs_panel_comparator.jpg\|\|thumb\|right\|102px\|]] Resistors RA and RB form the voltage divider that determines the gate output voltage. Use 1k for RB. When running off +/-15 volts use 1k8 for RA. When running off +/-12 volts, use RA = 1k5.
