I recently purchased this PL-A35D Ser. II turntable and I can't figure out why the tone arm wont go down all the way? I loosened the arm adjustment screw (Last pic) and the arm rest is all the way down I'm guessing? The stylus is about 3/8" or so above the LP. The armrest is loose enough that you can feel it bottoming out. I still have to go thru the whole thing motor, spring foams, spindle , clean and detail etc. Any thoughts? Thanks! ; )
