This is what the PCB should look like with all of the LEDs installed:
2-3) Next, insert the I/O Jacks, Ground Lift Switch and Attenuator Potentiometer into the front side of the PCB - DO NOT solder these
components yet. Note, the ground pin for the jack is the one outside of the molded plastic part of the jack. This is the pin that goes towards
the left and right sides of the PCB:
2-4) Once you have the jacks, switch, and potentiometer seated, install the front panel and then the jack nuts and nuts for the Attenuation
potentiometer and Ground Lift toggle switch. This will keep everything together while you solder the pins to the PCB. Tighten the nuts until
they are snug - no need to go crazy tight on them. If you are using pliers instead of a Knurled Nut Tool, be careful not to scratch the front
panel. Check that the front panel is parallel to the PCB. If not, you may want to install the potentiometer washer between the top of the
potentiometer and the back of the front panel:
