Beogram grounding question

[Pacoloco]

Hi all. I am new to beograms and have a question about adapting the din phono cord
I see many adapters for sale that terminate with RCA plugs but no separate grounding wire. is the ground built into the RCA males adequate for use? Or do I need to find one that has a separate ground wire?

The shell of the DIN plug is used for grounding and in an adaptor, this is usually taken to the shield of the phono plugs. As a result, you shouldn't need a separate earth lead.
