It is true that some turntables doesn't have a grounding wire so they use an internal grounding instead (some Regas are like this), but the Dual CS 505-1 has a separate grounding wire. Perhaps it is missing on your sample? (the wire is thin and weak, perhaps it was broken...)

Here is the instruction manual...

Anyway it seems like you got it sorted out so that's good... :)

Raphael: Another possibility is that Neep's exemplar could have originally been equipped with a DIN plug cable and converted to RCA/Cinch later on. Unfortunately this often was (and still is) done not quite correctly, as quite a few people don't seem to understand the difference between the two grounding schemes involved...

Ah, the DIN plug... forgot about that. :)
I have read somewhere that DIN plug is a superior solution for grounding, don't know if it's true.
Today they are rarely used.

Raphael: Well, in theory one could use separate shield and signal ground with DIN cabling - but in practice it's hardly ever done that way (in fact you'll usually rather see combined ground configurations...). So, if anything, DIN cabling has a slight plus in terms of convenience, as the user needn't care about left & right - and one only needs one cable for connecting a recorder (so the user also needn't care about signal direction). However, on the other hand no left & right also means no convenient channel swapping for problem diagnosis - and cables and pins are pretty close together, so that there can be increased crosstalk. And if one is honest, one has to admit that regular consumer grade DIN connectors and ready-made cables typically were only of mediocre quality - and nowadays it's already rather difficult to find decent DIN plugs at all, even over here in Germany. I guess, if they had gone for higher quality XLR style plugs and jacks insteas, my opinion might be different - but in the usual form DIN cabling really existed I actually don't miss it at all. Even more so the bulky "Würfel 5" DIN connection for headphones - and the rather wimpy DIN connection for loudspeakers, which is only good for rather thin cables. So I was actually happy to see the DIN cabling being dropped pretty rapidly in the early 80s.

And, just by the way, I never was much of a fan of our European Scart/Euro-AV connection, either. Granted though, that packed quite a few in- and outputs into a fairly compact connector, so I can see why the manufacturers went for that...

Thank you Manfred for your explanation..
Naim used to use the DIN connector for a long time, I don't know if they're still using it, but the main reason for keeping it so long was that they felt it sounded the best - but then, they had their own DIN cables...
