Empire with 1980 Theatrical Stereo:
Jedi with 1983 Theatrical Stereo:
Also, I just discovered a 1984 Japanese Empire LD that has the English 1980 theatrical audio track, and also is not time compressed:
And possibly the same for Jedi:
Also note that I have no idea if there ever was a 1985 remix for Jedi (though I'm fairly certain there was a 1993 remix), so it's possible that the Japanese Special Collection (with the 1985 remixes of Star Wars and Jedi) and its related US releases contains the 1983 stereo for Jedi, as well.
But I'm not 100% sure on that.
