OK, thanks!
Sorry for taking so long to respond, I was away at school. I removed the 2 pins from the BM 2400 end of the cable and played a record. Strangely, as soon as the tone arm came down on the record, a buzzing noise could be heard throught the speakers. Then, as the music began to play, the noise faded but never went away entirely.
Does anyone know why this might occur? Before I had started this post, I had connected the BG 8002 to my 2400 with all 7 pins intact and no buzzing could be heard, however, I could not turn the reciever off with the cable this way.
Thanks again,
Aaron
