[Yaesu] FT one Power plug

[zl3kr]

can anyone tell me where I might be able to get hold of one of the
four pin in-line plugs that connect from the power supply to the radio.
I currently have a power supply problem and  want to try and connect
an external power supply to  the rig to get it back on the air in the 
mean time
and the easiest and safest way would be to use one of those plugs to 
connect
straight into the radio certainly with less liklelihood of disastrous 
blow ups.
