AR XA Assembly Post shipping.

Mark, hang in. The 2 groove drive spindle is the motor pulley. The different grooves relate to the 45rpm and 33.33 rpm speeds that the platter is designed to turn at. When you turn on the motor, this should turn. It should not wobble. Then again, if it does wobble, there is not much that you can do to correct it without a machine shop. The belt only goes around the sub platter, not the outer platter. If it comes off of the sub platter, or off of the pulley, it is usually a matter of tuning the three bolts that adjust the springs. If you have a camera, send me a photo off board. It has been many moons since I have had one. Alernately, contact Wendell Narod, user name Narod, he uses one in his second system and can probably help as well. Just be patient and non judgemental. Sometimes one is proceeding forward but looking in the rear view mirror and it looks as if one is proceeding backwards at a rapid pace.

Usually the AR tables have a "lockdown" screw or bolt that locks the suspension down for shipping. You will need to remove this. Also the belt won't ride correctly until you put the platter on the subplatter to offset the weight/height difference of the sprung suspension.

OK, Newb mistake #1.

Suspended board won't balance until tonearm installed.
Don't judge a book without a binding.

More to come, more to learn, obviously
