Thanks a bunch for the response. I have cleaned the inside of the platter rim and motor spindle with isopropyl alcohol. I also "ruffed up" the idler wheel as per the instructions on this page: http://dual-reference.com/Troubles/speedcontrol.htm
I am still having the worbel effect, just as described on that same dual-reference page.
Two things that have noticed. The with the platter off, the idler wheel does not engage with the motor spindle in 16, 33, or 45 speeds. You have to push it a bit to get it to engage. Should it be?
In 78 speed it will engage and it makes a bit of a squeaking sound and seems to wobble a bit.
I did apply a small bit of oil to the screw holding the idler wheel on as I noticed that was a lube point in the manual. This helped the squeak a bit, but still getting the worbel, especially with piano (sounds like a cat dying).
My next idea is to take apart the motor, but I hate to do it as it seems like a nightmare.
Also, could the sound be coming from a bad needle? I noticed my needle was bent slightly to one side and I had to straighten it a bit. Maybe the motor is fine and I need a new needle?
Thank you, I hope I haven't been off more then I can chew!
