Thanks Dillen and Peter. Yep, it appears it was simply the fact that I didn't have a record on the platter. I didn't realize it had a record-weightng device. So now at least I know that the turntable works in that respect!
Two more quick questions: First, I haven't actually had a chance to play a record, so I don't know if the stylus needs to be replaced. Are there any budget recommendations you can make? Second, while the belt does turn the platter, I assume it's pretty old. Does it make sense to just go ahead and replace it, given the relatively lost cost?
Thanks again for your help
Matt
