I pulled the whole thing apart and I removed the brown glue.
There was a fair amount of corrosion happening around the top of the coils, especially where they crossed the bottom side of the terminal strip. I scraped it all off and all the brown glue.
Unfortunately, this didn't seem to be the problem. When I got the coils out and measured them, I found that each side was 0.48 ohms exactly, so I'm convinced that the Sams was giving the DC resistance per side and not the whole thing. This was with all the glue gone and no coils touch each other at all; this inductor is wound very loosely and doesn't overlap.
So I don't know what to do now.
Another symptom That I didn't think to mention is that when I change the horizontal size, the brightness of the raster changes. It gets darker when make it smaller. Pretty significantly darker actually. Now that I think about it, this seems fairly significant and wrong.
