Zenith Stereophonic Model X966D

I have a Zenith Stereophonic Model X966D that I inherited from my grandmother.

I know nothing about this model and what it may be worth. Can anyone help me out? It seems to be in good condition with only slight warping on the top that is really not noticeable to the naked eye. I know that the AM/FM portion of the stereo works but am unsure of the turntable.

Thanks!
