See attached for a vintage entertainment center that I am trying to help refurbish. Known to be General Electric, probably manufactured in Decatur, Il. Patent numbers on the back indicate three patents dated 1960, 1963 and 1964. I am trying to remove the turntable to either refurbish it or replace it. I have not been able to determine how to remove it from the cabinet (after many hours of research on the Web). In the stored position, it is vertical. In the working position, it folds down like a secretary desk. Does anyone have any suggestions? Thanks for any time that you have to spend on this!
