  • The Murphy TA224R bandspread radiogram.

    Why the emphasis on music? Because this fine new Murphy radiogram, the A224R, is first and foremost an instrument for reproducing music. And it fulfills this function supremely well.

    The A224R will give you the kind of reproduction you've often dreamed about and never heard from all your records standard and long-playing, classical and swing. There are two high-quality pick-ups, one for "ordinary" (78 r.p.m.) records and one for " long-players" (33⅓ and 45 r.p.m.).

    Various circuits, including a frequency-selective negative feedback path, give ample bass compensation, and you can get the exact amount you want for any record by turning the bass control. To complete the reproducing process there's a very special extra high flux density 10 in. loudspeaker which gives the set a sound volume as high as any on the general maker today. And the quality of reproduction is maintained too, even at such great volume.

    In between listening to your records, you can roam the world with the radio side of the set. The A224R has a remarkable range on its eight wavebands, and to help you get the station you want there's band spreading and a "magic eye" tuning indicator.

    When you don't want to listen to anything at all, you can just sit back and admire the cabinet-it's veneered in pomcle and sapele mahogany and it's well worth looking at.
