- The schematic is the same for Arvin models 617 and 627. They have three bands whitch show in different colors. The Arvin model 627 Rhythm Master with 7 3/16 inch dial from Noblitt-Sparks covers 560 - 171 meters (Green, 535 - 1750 kc), 176 - 52.2 meters (Yellow, 1700 - 5750 kc) and 54.5 - 16.65 meters (Red, 5.5 - 18 mc). One electro dynamic speaker 10 inch. 3-gang condenser, continuous 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-627 Rhythm Master and sets a price of $ 134.10. 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.

I obtained a radio dial belt number 185, manufactured by General Cement, which is specified for the Arvin 627 from a local parts supplier but it is too tight and as a result the fine tuning mechanism does not function (it slips). I measured the belt and it is shorter that the what is specified on the package for the number 185 radio dial belt. I tried other belts of that size as well as belts that were next three lengths longer and they all either were too tight and caused the fine tuning mechanism to slip or too loose and caused the belt to slip on the pulleys. I taked to the supplier and the belts are 50-60 years old and it is likely that they have shrunk over time. Is this a common problem? Is there a simple cure for this problem short of installing a belt tension idler? Thanks.
