[R-390] UnBal for R-390A

Has anyone made a un-bal for the balanced antenna connection on the R-390A
to bring it down to a 50 ohm unbalanced connection?

I have a hand-wound 2.5:1 balun with overlapped windings with Litz wire on a
FT-75 core (125 ohm to 50 ohm). What I would like to know is if I should
make another one of these things for my other receiver or I should go the
easy route and use a single wire into the unbalanced connector or just use
the C connector for my antenna.

My guidebook has been;
www.dxing.info/equipment/*impedance*_*transformer*_bryant2.doc<http://www.dxing.info/equipment/impedance_transformer_bryant2.doc>

It seems that most folks get great results with the easy route. What have
been your experiences?

Any suggestions?
