Well I was close. The article by VE2CV ("Transforming the Balun") is on
page 30 of June 1991 QST. It describes using a pair of 93 ohm cables in
parallel with ferrite beads to make a balun. However there are references
in the Notes section of this article to other articles where balanced
feeders were constructed from pairs of coax. I also seem to remember that
Belrose did a follow-up article on running parallel coax lines.

(Jack Belrose) wrote an article about this very thing in QST just a few
years ago. I'll have to track down the article to be sure we're talking
about the same thing.
