Phonograph only outputs left channel?
It's a Beogram 8002 phonograph and a Rotel RA-8408X amplifier. Much to my dismay, the phonograph appears to only be outputting audio to the left channel, even with a stereo LP. The speakers are wired correctly (I've confirmed that, using a different source, the speakers output stereo), and everything is plugged in as it should be. I've checked the audio cable(s) that goes from the phonograph to the amp with a multimeter and didn't find any shorts. Curiously enough, the plug that goes into the phonograph (it appears to be proprietary) has 5 pins and a ground, but only 3 of the pins do anything. Apparently this setup cost my Dad a pretty penny when he bought it, so I'd really like to fix it. Any help is appreciated.
