Alright. I'm at my parents house now, trying to hook up their old equipment. It consists of an old (Don't know MN, circa 1990) Sony reciever, and a pair of kickass Polk Floorstanders. Anyway...I can only seem to get the damn thing to work in mono. I hooked everything up, like I've done a dozen times before...and nada. I tried playing a CD and listening through my headphones on the CD Player...stereo all the way, but when I go through the reciever, nada. I found the old manual, and it says that the stereo light should go on when a stereo source is playing...but I can't even get it to come on on the tuner. Any ideas...any guru's out there who see the error of my ways? Thx.
