Grundig Majestic info

Hi I have a Grundig Majestic console SO 190 Ua1 radio/phonograph/reel to reel. It's a big dark wood wheeled unit with the speakers across the bottom. It's got an FM shortwave radio in the center that works and the phono works too. According to the schematic on the back, it has twelve tubes. It's in pretty great shape for how old it is. I'd like to more info on this model, what the value might be and also either figure out how to tune it up myself or hire someone to help me with it. I'm in the Los Angeles area. Any info would be appreciated. Thanks, Chris
