I think it's not a duplicate, cause there is a linear FM-Input added.
Please, note also the link to navsmodularblog.

What a cool mod - hats off for navs!
(not a duplicate obviously)
Maybe name it "Doepfer A-143-9 navs Lin FM mod"...
There. It has been un-privatized. :)
However, I'm not sure every modification to every module deserves a new entry. It waters down the module counts and add confusion. For instance, what if someone thinks such modules are actually available.
