B&O wire colors

I've recently unboxed my Beogram RX so that I could listen to my crates full of old vinyl that have been collecting dust over the past years. As I was getting the turntable setup, I found myself puzzled by the output wires. Rather than the red and white color coding I frequently see, these are colored black and gray. Does anyone know which color is the right channel and which is the left?

Thanks,
Bob Chmara
