    There were five versions of the cathedral 38B: Version 1 (1933) has the classic spade-shaped speaker opening used on many Philco cathedral cabinets. Version 2 (1934) has an oval opening with three vertical bars and downward curving additional bars at the bottom. Version 3 (1934-35) has an oval opening with stepped features at the bottom. Version 4 (1935) is similar to version 3, but has a larger escutcheon opening and new dial design. Version 5 (1936) has a cabinet with a continuous arch shape starting from the base and multiple vertical bars in the speaker opening.

    The model 38L lowboy has two versions: an early version (1933-34) with four narrow vertical bars at the edges of the speaker opening, along with other embellishment, and a late version (1934-35) with a single vertical bar through the center of the speaker opening, along with other embellishment.

    There was also a highboy (1933) and a floor-type console (1935-36).

    The chassis had an early version (used for 1933 and early 1934) with a type 15 mixer tube and a later version with type 1A6 mixer (used from mid 1934 onward). Chassis marked as model 38 have no ballast tube and are designed for use with a 2 volt storage battery for filaments. Those marked 38A have a ballast tube (type 6 early; type 1A1 late) and are designed for a dry battery (presumably 3 volts?) for the filament supply.

    Two Philco schematics are available: code 121 with type 15 mixer (also found in Rider vol 4) and code 123 with 1A6 mixer.
