Final Assembly
1. Place LED onto the PCB – do not solder yet
2. Mount PCB onto panel and tighten nuts
3. Ensure LED pokes through the hole on the panel, solder into place
4. Mount sockets PCB to panel and tighten sockets
5. Using cut off resistor legs, connect the two PCBs (see photo)
Calibration
The 10K trimmer is for Level CV zero offset. Correct set calibration ensures that the output from the
LFO socket is spot-on at 0V when the Level CV input sees 0V. This is particularly important when
using Wave Runner as a pitch vibrato source into a VCO with a mod wheel controlling LFO depth via
the Level CV.
1. Hook up the LFO output to a DMM
2. Ground the Level CV input
3. 3. Adjust the trimmer until your DMM reads exactly 0V
