I have a 1956 Telefunken Opus Royale Hi-Fi. It was my grandfathers. His five sons went shopping for it with him and bought it for him I believe. (they went store-to-store with one record that they played on all of the models they looked at.) Cost around $800 in 1956! I didn't believe the price until I saw an ad for one recently from 1958. Prices were from $300 to $1,600. They bought it at a high end furniture store in Cincinnati and had to wait for it to be shipped from Germany.
It has been refinished twice. First by grandfather's fourth wife who butchered it. More recently by my father. He did a nice job but did not return it to its original blond finish. I've been trying to find a picture of it in its original condition so I can get it back the way it should be finished.
Still sounds great. It even has an extra speaker cabinet to go with it. I think dad still has the record they used to test the Hi-Fi's. Maybe I'll borrow it next year and hold a 50th birthday party for the Telefunken. I not sure if any parts have ever been replaced in this unit. I don't think so.
