A few quick question for Kenwood fans in-the-know. I'm thinking about buying a Kenwood KR 7600 but I've never seen on in-person. They look gorgeous to me. 1. Are they difficult to work on? 2. Is it easy to get at the controls and PCBs? I've worked on a KR 4600 and it was a little tight. 3. IF I hold onto it for awhile, my primary use will be FM radio. How do they perform in this regard? 4. My secondary use would be vinyl. How is the phono section? Please let me know what you think. Thanks!!!
