I've just received a bare HV and neck board from Dezbaz too, but my neck board doesn't have the 12 (I think it's 12?) way connector on it. I think Dez recommends you solder the wiring harness wires directly to the PCB now. Perhaps worth you asking him to confirm before you build.
I've still got to source the MPSU-07 transistor though, along with a few other parts.
And that's too square a shape for a nine bar. Allegedly.
