Notes There are two versions of the 38-93B tombstone -- an early version with a round dial and the tuning knob in the center of the dial, and a late version with a rectangular dial, with the tuning and volume controls below the dial. The early version has a photofinish front, and the late version has a wood veneered front.

Philco service literature indicates that the 37-93 schematic is to be used for servicing the 38-93 chassis. Thus we may conclude that the two chassis are electrically similar. Note that the chassis for the early and late versions of 38-93B must be mechanically different, since the control locations and tuning mechanism are different.
