Sounding great so far. Initial testing was fine but on a better system revealed some ground loop noise which needs to be addressed.
ToDo:
Wire the 24v LED front panel for red/green.
Connect XLR pin1 to chassis.
Build Post-Mortem Notes
The deluxe chassis came with pre-drilled/tapped heat sink holes and pre-drilled back plate. On reflection both of these were more a problem than help. The heat sinks seem to have some residue marks from the pre-drill/taps.
The back plate layout does make the input connections too close to the placement of the ISS boards inputs.
Also the back plate flexes when the power cord is pushed in. The back plate overlaps the verticals but not the top/bottom ledges.
