  • The Philco model 118 series is similar to the model 18 series. Both use an 8-tube chassis with shadow meter (tuning aid) and a 10-watt push-pull class A audio output stage. The model 118 series has two bands, BC and SW (4.2 - 12 MHz). Chassis marked "118A" are for 25-40 Hz AC power, while those marked "118" are for 50-60 Hz. The code 123 chassis was used in the chairside model 118RX (see below), while other models most likely used code 121.

    There were nine versions of model 118, each with a different cabinet style. The early version (1934) of the 118B table radio had a cathedral cabinet, with scalloped top edge and a speaker opening with one large and two small openings. The late version (1935) of 118B was a shouldered tombstone.

    There were three highboys: Model 118H (1934-35) had six legs and a Y-shaped speaker grill. The early (1934) and late (1935) versions of the 118D highboy with doors are very similar; both have six legs, but the late version has "waterfall" moulding at the center of the bottom of the main body of the cabinet.

    There were three floor-type consoles: The early version (1934) of the 118X had a classical look, with three round pillars in front of the speaker grill, and patterned moulding around the top of the cabinet. The late version (1935) of 118X was simlar, but had a slightly more modern look overall, and an emblem in the center of the moulding around the top of the cabinet. The 118MX (1934-1935) was a modern-style cabinet, with two square vertical bars in front of the speaker grill.

    The 118RX chairside had a control unit and a large separate speaker cabinet, with the two connected by a 25-foot cable. The controls are located within a T-shaped recess on the top of the control unit cabinet, and the speaker cabinet has a large V pattern with "wings" on the speaker grill.
