Nifty old Zenith Chain Drive

[jstout66]

Sounds like you ran across a Zenith with a Cobramatic turntable. I think I have a Zenith repair book on Cobramatics. If it's the combo I'm thinking of (is it in a cabinet and has 2 pull out drawers in the front? On the left would be the turntable and the right the radio?) If it's that one they usually are a good performer.
