Hi Mike. I used to have the HA460, which was the 6 meter version. If I
rememvber correctly, the power cord is on of those 9 pin opto socket,
which alot of the old CB rigs had. You would have to get a wiring
diagram of the power cord if you could, as many of those tipe cords were
wired differently. Usually, 2 or more pins were jumpered as well as the
120 Volt input going to the proper pins. Good luck with your search.
