Nick, I am comforted by your discovery of convergence transformers. :-) BTW, that schematic is from a RCA CRT symposium, not a set I have.

I may be wrong (I often ma) about the mu-metal shield. The C73293 CRTs are shown to have an internal mu-metal shield. I don't have and explicit data on the C73547 CRTs, but the one in my Sparton also has a external mu-metal shield, so this would seem to indicate the C73547 series tubes use an external shield. Attached is an assembly drawing of the C73293 series tube.
