I bought these speakers for cheap at an estate sale as a project. I thoroughly cleaned all electrical contacts, refoamed both drivers, and replaced both internal capacitors. Work like they just came out of the factory. Perfect for an audiophile.

Original AR – XA TURNTABLE with Shure M93E Phono Cartridge & photocopy of manual. Unit has just been serviced. New belt, lube, De-Oxit, speed tested, played, etc. No platter mat (I used a cheap foam rubber one in order to test it). It Definitely needs a mat. There is a small hole in the top near the tonearm (see pics). There is damage to one corner of the oiled walnut base (see pics). Overall a nice, simple turntable at a reasonable price.
