My father had this part lying in a drawer, and said that it could be a B&O part.
only marking on it is the number 6140164

so question 1: is it a B&O part?

2: if so what is it?

thanks in advance

It’s B&O alright.
Not sure for what, though, but could be a RIAA, so perhaps an input adapter for a TV or a tape recorder.
Late 1960s or early-mid 1970s, I’d say.

And the 56K resistor has a bad solder joint. Perhaps the reason it was replaced.

Thanks for the answer. Looking closer I can also see that the DIN connections are definitely not B&O standard connected. It seems that pin 1, 2 and 4 are all connected across the 2 DIN plugs, and pin 3 are connected to pin 5 on the other connector.
