Are there any Delphi Oracle Users Who Can Comment

The one I was looking at ( now I have looked at the Oracle website Legacy products) appears to be the very first incarnation of the Delphi, the Delphi AC, just one year I think.With a bit more research it might be more prudent to look at much newer tables without 40 years of usage?

And that seems to be the issue I have, defining a well maintained Oracle.
What to look for?
After reading a couple of threads on the Magnepan Unitrac arm I may have found one major issue to begin with (on the one I was looking at )
It appears the seller has "cut the ends of the tonearm lead"
Not 100% clear just why yet but by all accounts it is near impossible to run a new tonearm cable through this arm?
So that would mean a new arm for sure I think.

I am looking at an Oracle Delphi right now with view to purchase.
What points do I need look for?
Potential problems or flaws?
This one has a Magnepan Unitrac 1 carbon tone arm and Denon 305 included.

Thank you
