• Notes

• The Philco model 37-2670 series is the export version of the 37-670 series, with different band coverage and power supply options. The 37-2670 chassis, like the 37-670 chassis, is an 11-tube 5-band chassis with shadow meter (tuning aid). Band coverage is 150-350 kHz (LW), 530-1600 kHz (BC), 1.6-4.8 MHz, 4.6-11.5 MHz, and 11.5-22 MHz. Power supply voltage is selected between 110 and 220 VAC (50-60 Hz) through the use of a plug which is inserted into a socket in two different orientations. There were also versions for just 115 VAC, with either 50-60 Hz or 25-40 Hz (using different power transformers, depending on line frequency). The schematic specifies the use of -E suffix tubes, which are ruggedized versions of standard tubes.
  
  There are three specific models in the series with different cabinet styles. Model 37-2670B is a tombstone. The early version of 37-2670X is a console with a nonrecessed control panel. The late version of 37-2670X has a recessed control panel (among many other cabinet design changes).
  
  The 37-2670 series design continued into the 1937-38 model year in the model 38-2670 series.
