• This model page will be the primary source of information for all the 517, 547, and 5517 family models and should be referenced on those related model pages.

  The Crosley "Fiver" family was introduced in 1937 with two models: 517 (early) and 547 (early), both with the same chassis schematic. The 547 model added the "Teletune" option, easily identified by the telephone-like escutcheon with telephone-like tuning. The early models are 517 below S/N 4032104 and 547 below S/N 4338751. The early model Dials had the Foreign band on top and the Broadcast band on the bottom. These models came in several different cabinets; tabletop and console.

  In late 1937 or early 1938, they updated the schematic slightly and identified the models as 517 (late) and 547 (late), and added the 5517 model. The late models are 517 above S/N 4032103 and 547 above S/N 4338750; this update applies to all 5517 S/Ns. These models came in several different cabinets; tabletop and console.

  Note that the 567 Chairside models were introduced at this later date and are schematically similar to the 517 (late) except the large filter capacitors were moved from the chassis top to the chassis bottom, perhaps for cabinet clearance issues. They have their own schematics, so they are not referenced here.

  Some of these updates were:

  • Added optional power transformers for 110 V, 50 Hz and 220 V, 50 Hz.
  • Some models may have an added wave trap with a tunable frequency near the IF 455 kHz. This was added to eliminate interference from code stations operating near the IF frequency. This circuitry was located on the chassis bottom, next to the Antenna/Ground terminals.
  • Some component/wiring changes to the volume and AVC circuitry.
  • Late model Dials had the Broadcast band on the top and the Foreign band on the bottom.

  Some of the visually identifiable differences between the models, early and late are shown in the following table.

  Model	Teletune	Dial Bands (Top/Bottom)1
  517 (early)	N	FN/BC
  517 (late)	N	BC/FN
  547 (early)	Y	FN/BC
  547 (late)	Y	BC/FN
  5517	N	BC/FN
  55172	Y	BC/FN

  Notes 1   The two bands are printed on the top and bottom of the Dial. They were reversed
                  from early to late. The pointer is airplane style. FN=Foreign, BC=Broadcast.

             2   Documentation is unclear if the 5517 Teletune model has a different number,
                  so it is assumed to be 5517 for now.
