Funny you should mention it, I've never seen an actual change in picture linearity when messing with that coil. On the Philco B&W set I had though, it had a huge effect on screen images.

If you can't find a dip on the 7, look at replacing the resonating caps around the coil. Sometimes these have a 1500 volt rating.

See, that's what I though too! But I tried replacing the .1 across the coil with a .047, and current ranaway to 250ma+ before I pulled the plug. After that I tried a .2, and it didn't seem to make any improvement over the readings with a .1uf cap. All the ones that are in that part of the circuit are what the schematic calls for right now, so I'm not sure where to go with this next.
I suppose it's possible that there are some funky turns on the efficiency coil itself, so perhaps I should try slaving in the known good one from the 9 next?
