Where can I purchase 72 ohm balanced feed line that was popular in the 1960s. It was low power and about the diameter of your small finger and tubular in shape thought it was called twin lead?

That was sometimes called "oval line". I haven't seen any in quite a while since everyone started going to coax for TV. However, zip cord is about the same impedance. What frequency range are you looking at...if it's H.F., good quality polyethylene zip cord is okay....just don't try it on VHF!
