In browsing the local Craig's List ads for CRT TV's, I noticed this ad for a bpc GE TV, looks to be about 27", and judging from the jack panel, a fairly top of the line model for GE. But check out the pic of the jack panel in the second photo -- what do the two slide switches labeled as "picture tilt" do? I've never seen this type of control on a conventional CRT TV before.
