Hi Pete.

Thank you for your efforts.

Your efforts to characterize and describe components are undoubtedly helpful to many others.

Thank you for your images.

They looked familiar.

Attached are a couple of images comparing images of the original CM-777x to your image of the RCA preamp.

The image below is the coil/switch side of the PCBs.

Notice that the coaxial connectors are on opposite sides of the PCBs.
