These are the circuit boards I made from "Paxolin" sheet. Brass eyelets with 3mm through holes have been fitted for use as point to point solder contacts. The six large holes just off centre line up with the six binding posts I have already fitted to the cabinet. The boards will be secured using 16mm M4 stand off's, this will position them just  above the block of wood on the rear face of the lower compartment, that Celestion added for mounting the binding posts. Plus give additional clearance to accommodate the plastic spacer bar that each pair of binding posts I have fitted is secured by.
