Unfortunately defective - would have been otherwise nice!

I want to give this music system for Christmas to my father, because he things from the 50's and very much older. The first impression was good - housing made of wood, good looks, only the platter made a somewhat unstable impression (loose plastic). In the first test, the system worked flawlessly, even on Christmas Eve they provided a positive surprise and much joy. Unfortunately, the anger then began: at each start-up there was a loud humming noise or vibration and which even drowned out loud Asked music. Apparently, the processing inside is not the best - sounding as if Diaphragm breakdown or loose parts. So unfortunately everything back and disappointment on the part of the recipient and the giver!
