Don't know the part number off hand, but it is a common item and I think
the same cable fits a number of Kenwood's and maybe some Icom's as well.
So if the power supply is bad, why not just cut the wire off and attach
it to the Astron?
Don't know what is on the power supply end of the cable attached to the
PS-430, but you can just cut it off and attach the wires to the large bolts
which are the terminals on the Astron.
Good luck, Steve KW3A----- Original Message -----
