• Notes
• Philco's model 34 series used a 4-band (BC - 23 MHz) 7-tube chassis powered by batteries. The standard model 34 chassis used a 2 volt A supply from a storage battery, while the 34A chassis was designed for dry battery A supply and had an extra ballast tube in series with the A supply, presumably to lower the A supply from 3 to 2 volts. Both types of chassis used two separate -3 V C batteries, one with a connection common to the other batteries, and one independent.
  
  There were three versions of the model 34B table radio. The early version (1934) used the flat-front version of one of Philco's classic cathedral cabinet designs with spade-shaped speaker opening. The middle version (1934) used a different cathedral cabinet with a scalloped top. The late version (1935) was a shouldered tombstone with a lyre-shaped speaker opening with three vertical bars through the center.
  
  There were two versions of the 32L lowboy - an early version (1934)with four mostly-vertical bars through the speaker opening, and a late version (1934-35) with nested V- and W-bar patterns through the speaker opening.
