An Emerson with a 19AP4??

Looking at the picture in my Sams (page 16), it appears that there is a cap connected to the end of R-7... it is standing nearly on end, and identified in the picture on page 9 as C-45. C-45 is shown as a .05/400 volt cap that is connected between the wiper of the brightness control and the minus 185 Volt supply. Since the vertical lin control also connects to the -185 Volt supply, perhaps it is being used as a tie point for the -185 Volt line. If that is true, then it is not clear *why* that point is also tied to R-64 in the focus divider.
I would think that some careful tracing out of the connections related to the -185Volt supply might be necessary at this point in time, as it is not clear that schematic that we are looking at (Sams) represents the wiring observed in the chassis. How does the Sams compare to the factory schematic or Ryders in this area?
