• Anotaciones
• The model 18 series included fifteen models with various cabinet styles. The first version of the eight-tube chassis (1933-34) had two bands (BC and 1.5 - 4 MHz), and the second version of the chassis (1934-35, code 124) had a single band (BC only). Both chassis had a shadow meter and a class A push-pull 10-watt audio output stage. In 1934, the similar model 118 series was introduced, which again had two bands.
  
  The early version (1933-34, with chassis v. 1) of the 18B cathedral had one of the classic Philco cathedral designs, with spade-shaped speaker opening and recessed panel. The middle version (1934, with chassis v. 2) had a new cathedral design, with scalloped top and a speaker opening consisting of one large opening with smaller openings to the left and right side. The late version (1935, with chassis v. 2) was a shouldered tombstone design.
  
  There were two lowboys: Model 18LS (1933, with chassis v. 1) had four mostly vertical bars through the speaker grill, and an arched control panel. Model 18L (1933-34, with chassis v. 1) was a more ornate design, with four narrow bars through the speaker grill at the sides, along with other embellishment.
  
  The early version (1933, with chassis v. 1) of the 18H highboy was an ornate six-legged design, with six narrow vertical bars and other ornamentation on the speaker grill, and an arched control panel. The middle version (1933-34, with chassis v. 1) was also six-legged, with two mostly vertical bars through the speaker grill, and a rectangular control panel. The late version (1934-35, with chassis v. 2) had a Y-shaped speaker grill with vertical bars. There was also a model 18D highboy with doors (1933, with chassis v. 1) and six legs.
  
  The 18RX chairside (1933, with chassis v. 1) had a separate large speaker cabinet and used the same cabinet as models 14RX, 16RX Early, and 17RX.
  
  There were five floor-type consoles: Model 18XS (1933, chassis v. 1) had a large open speaker grill on an inclined sounding board. The early version of model 18X (1933-34, with chassis v. 1) had a classical type design, with three round columns in front of the speaker grill and patterned moulding around the top of the cabinet. The late version of 18X (1934) had the same cabinet, but with the second chassis version. The early version of 18MX (1934, with chassis v. 1) was a modern design with two vertical bars in front of the speaker grill. The late version of 18MX (1934-35) had the same cabinet, but with the second version of the chassis.
