Of note: The frequency pot CW and CCW connections are shown as per the original VCF, i.e. backwards to standard convention. I would suggest you swap these wires!]]

Take this opportunity to sand the edges of the board if needed, removing any splinters or rough edges. (With the boards supplied by me, the edges are already milled, and etching faults are very rare.)
