Radio Broadcast (May 1927-Apr 1928)

RADIO BROADCAST ADVERTISER 253 A cone loud speaker A complete set of A-C tubes An "A" battery and charger combination A kit A radio table (a good one). Twenty-Five Dollars to Fifty Dollars We now leave gifts to the family and friends and consider presents for elevator boys, postmen, janitors, ice-men and others requiring special attention. A very fine cone or Balsa speaker. A veil-designed "B" and "C" batteneliminator. A kit From Fifty Dollars up We started with gifts for the family, and we conclude with the same. If there is a very expensive bit of apparatus for which you have long yearned — some deluxe speaker, perhaps a Norden Hauck Super or a Radiola Borgia model, or maybe a Wheatstone Bridge or a Leeds & Northrup type K potentiometer— why give it to the family for Christmas. And in closing let me advise you to do your Christmas shopping early — early on the morning of December twenty-fourth. TO (RADIO 'DEALERS! The R. B.
