Source for Marantz 1060, 1030 and other models shielded hook up wires ?

[Rapide]

There are 15+ shielded single stranded conductor cables in every 1060.. 6 different colors.. mostly about 12” and 16” .. that fray, break and shorten after 60 years of unsoldering all the wraps, rebending and resoldering. The last (4) 1060’s I worked on all could have benefitted from one or more original color new cables. Is there a source for these shielded colored cables.. ideally with a stranded center conductor one gauge larger ? As an Unshielded example: Fermerry (photo), and other AZ vendors, have handy tinned silicone cover stranded wire hookup kits in multiple gauges and colors.
Thanks in advance !
