Old Vinyl I have a ton of old vinyl, early 60's all the way through to early 90's (cheers Dad). Used to play them on my stereo turntable, but since I got some decks, been playing them on there, not only to listen to, but to mix with. Is it ok to use old vinyl in this way? Will they lose quality quickly? Don't wanna fuck them up as some are worth quite a bit I'm told
