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. Line 129: === Notes === * A 10 to 22 ohm resistor can be used instead of the ferrite bead. If you don't care about power-rail noise, just use a link instead. == CC-BY-NC == Readers are permitted to construct these circuits for their own personal use only.
