I received as a gift a VV2-55 portable! (I'm starting out small.

I'm having two problems with the turntable, however, and hope someone can help me. Something seems to be dragging on it. The brake lever only moves about an ⅛ of an inch, if that much. Same with the auto-shutoff thingy. If I wind it up and press down on the brake lever, the turntable turns but as soon as I let up the pressure, it stops. It seems something is jammed under the turntable. Guess my first question is, how do I get the turntable off?
The other problem is the speed control (maybe related to the above???). If I get the turntable spinning as described above and with my free hand move the speed control, I can see it slow down OK. However if I move it in the 'Fast' direction, when I get about ¼ of the way to the end (fastest position), it makes a racheting type of sound.
Any ideas?
