(Maybe you know this info, but just in case) Vintage turntables including the 1200 have a ground wire attached, if it's not connected to a receiver/preamp with a ground terminal, it will buzz. Check that you customer has done that before you swap out the turntable. Good score on that second turntable, i can not find one here in FL for less than 500-800. As always, Thanks for sharing your picking.
