• Anotaciones
• The Philco 650 series (1935) is based on an 8-tube 4-band chassis with shadow meter (tuning aid). The band covereage is 145-390 kHz, BC, 2.2-2.6 MHz, and 5.8-18 MHz. The standard 650 chassis uses 115 VAC 50-60 Hz power, and the 650A chassis is for 115 VAC 25-40 Hz.
  
  There are six individual models in the series with different cabinet styles. Model 650B is a shouldered tombstone.
  
  Model 650H is a short-legged console (not really a highboy, even though Philco uses the -H suffix to designate a highboy) with controls under a small lid on the top of the cabinet. Model 650X is a floor-type console with inclined sounding board and controls on the front of the cabinet. Model 650MX is another floor-type console with controls under a lid on the top of the cabinet.
  
  Model 650RX is two part radio with a chairside control unit and a large separate speaker cabinet (the speaker cabinet itself being as large as a console radio).
  
  Model 650PX is a console radio-phonograph with a 78 RPM single-play phonograph under the top cover.
  
  The tombstone 650B, with its smaller cabinet, uses a smaller speaker and a code 121 chassis. The other models use a larger speaker and a code 122 chassis.
  
  The model 650 series was superceded in 1936 by the 655 series, which is electrically similar, but without the long wave band, and has updated cabinet styles.
