  • Remarques
  • Home battery radio, drain 2.7 Amperes. Synchronous Mallory Vibrator for +B. The models 517 and 527 share the same chassis - with suffix "B" they are battery sets with an other chassis but the same cabinet than the same without "B". The early version Arvin model 517 Rhythm Junior is without the three vertical bars on front of the loudspeaker. The Arvin model 517B Rhythm Junior with 6 3/16 inch dial covers 545 - 171 meters (550 - 1750 kc = incl 1600 to 1700 police bands) and 16.65 - 52.6 meters (5.7 - 18 mc). One permanent magnet dynamic speaker 6 inch. 2-gang condenser, 2-point tone control. Cabinet in rich-grained walnut in combinations with pencil-striped mahogany and satin wood.

    Rider's shows that the chassis has been published 1936 (or before). The Belknap Hardware & Manufacturing Co. Catalog of 1937 features this model as E-517B Rhythm Junior and sets a price of $ 79.89 including tubes less battery. Pages 1053 to 1056 show a whole model family for "Rhythm". The family is in that catalog shown with a prefix E- whereas schematics and other ads show the models without this prefix. The "E" could refer to this catalog only since also a storage battery U17 or U175D is here called E-U17 and E-U175D. But we have to add the prefix so that users do find if they put it in.
