TAC MATCHLESS

[Neve]

I now need to find all the necessary supplies from a reliable supplier (ideally in Europe) to make those cables [any ideas], and then buy the patchbays...
I'd like to use 6.35mm jacks, not Bantam. They are way too expensive for me at this point, and nothing justifies that purchase.
The manual gives an idea of the way it's wired, but nothing too fancy. without having the assembly in front of me, I'd have no idea how to properly do it.

Thank you all for your valuable time and support.
