I recently removed a Becker AVUS (the S might be a 5) very analog radio from my Euro 300D, replacing it with a digital radio and cd player. The Becker is available for the cost of shipping; first come, first served. Its sound quality is really quite good for what it is, and its fm reception is excellent also. Its am reception seemed a bit weak to me, but I do live fifty miles from the nearest transmitter. This radio is for you if either you're nearly broke or you want to an authentic period replacement. Note: there's outputs for front speakers only. My Euro 300D is peasant class, so there were no rear speakers on board when it was shipped to the US of A.
