Zenith MH2615 Console With 9H20 Chassis

I just purchased a Zenith MH2615 console with #9H20 Chassis. It has AM/FM stereo radio and a turntable, both in brilliant working order! Looks to be perhaps from the early 1960s. I'd like to know more about this model if anyone has info. I paid $15 for it at a garage sale and couldn't turn it down when the lady kept offering other stuff to go with it just to get rid of it! - ended up with 134 old LPs and a couple of 1970s cameras.

Also, how can you get water stains off the wood?

Thanks very much!
