Stromberg Carlson TC-19 horizontal line

Hi all. I got an old Stromberg Carlson TC-19 TV from the late 40's or early 50's. It does power on, and I can get audio fine, but it only gets a single horizontal line on the screen. Tubes are new to me. I am trained in electronics but my training only covered solid state and digital, almost nothing about TV, radio or vacuum tubes.

I have been studying vacuum tube theory, and I do grasp most of it now.

I have the schematic and have done some diagnostics but am at a loss what I am missing. I have tested the yoke and seem to have continuity there. I know the problem must be in the vertical circuits some where. So I will be asking some questions when I get this set opened up again. I also know a full replacement of the old capacitors should be done to this thing at some point.

Here are some pics.
