Onkyo Integra Super Servo Cable

Good Day!

I am in need of the Super Servo Cable designed for use with my Onkyo Integra P-306RS and my M-506RS. I love these components and have had them for many years. Unfortunately when I took them to a local repair shop they not only didn't figure out how to fix them, they "misplaced" my valuable cable set. The repair manual lists the part number as: 2010068

Does anyone have such a thing such as an NOS set of these cables? If not, do you know where I could look in hopes of finding them? New or used?

I would appreciate any input that may be deemed useful. Thanks!
