• Notes

• 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. 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).
