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. |

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. |
