• Anotaciones
• The model 17 series was similar to the model 18 series of high-end multiband receivers, but had only two bands (BC and 1.5 - 4 MHz) and fewer cabinet styles. It was also less popular and was sold for a shorter time than the model 18 series. Like the model 18 series, the 17 series had shadow meters (tuning aid) and QAVC ("quite automatic volume control"), a squelch circuit to quiet noise between stations.
  
  There were six models in the series: Model 17B (1934-34) was a cathedral. Model 17L (1933) was the earlier of two lowboys, with four mostly vertical bars through the speaker grill. Model 17LS (1933-34) was the later more ornate lowboy, with four narrow vertical bars at the sides of the speaker grill, along with other embellishments. Ramirez mentions that some model 17LS radios are incorrectly labeled as "17B." Model 17D (1933) was a highboy with doors. Model 17RX was a chairside with separate large speaker cabinet. Model 17XS (1933-34) was a floor-type console with inclined sounding board.
  
  The chassis used in the 17B cathedral used a type 80 rectifier, while those used in other less compact models used a 5Z3. There was a version of the chassis designed for 25-40 Hz power, and these chassis are marked as "17A" (with the -A being a chassis suffix, not to be confused with the suffix of the main model number, which designates cabinet style).
