I tried to use the Yusynth VCO Kicad .sch but it was v6 or pre V6 version and threw up tons of violations downloaded the last update and it still didn’t like it. So back to the original diagram and do it myself which has been an enjoyable learning curve as has trying to update the “itmatters” updates. i just want to make sure the LM311 is wired properly firstly and further comments appreciated. Here is the github link!! please don’t laught too loudly. Chip90125/Yusynth_VCO
