How about Westminster in Phille? Orthodox Presbyterian.
Also there are Reformed Seminaries - I think at least two, one in Mississippi, and one in St. Louis. There may also be another one in Florida. However I may be mistaken -all you have to do is a search on the web. I think the PCA recognizes these, since they are an amalgamation of Reformed Presbyterians and conservative Southern Presbyterians in 1973.

Dallas Theological Seminary's professors are mostly Amaraldians. Some of the students are probably 100% TULIP though. One of their professors in the 70s, S. Louis Johnson was fully TULIP. He is now deceased. Ryrie in his Basic Bible Doctrines espouses unconditional election.
