There are two ways to go. You can download a variety of them at the Vinyl Engine, or you can buy a nice mirrored one for turntablebasics. com. It will cost you $20, but it is worth the difference.

if you google-up turntable protracktor, you may find tons of sites offering to print it out free, but still it makes more sense to buy it from turntablebasics.com as suggested above.
