Just as many other manufacturers were doing at the time, Philco offered its own shortwave converter at the beginning of 1932. This unit covers three bands from 1500 kc (1.5 MC) to 19 MC. Unlike many converters offered by others, however, Philco's Model 4 had its own power supply.

It operated by being hooked up to an AM radio which was then tuned to 1000 kc. The SW converter was then turned on, and was used for tuning in shortwave stations. It works very well.

Original selling price: $39.50
Number made: 7,029

NOTE: Tuning knob shown is incorrect; it should be the large "rosette" type.

The successor to the Model 50 used a superheterodyne circuit and five tubes. Some Model 50 chassis have been found in this style cabinet.

Philco's first high-fidelity efforts were built into a special cabinet with a speaker board known as the "Inclined Sounding Board" which was tilted up at a specific angle. The intent was to aim high-frequency sounds, which were believed to travel in a straight line at the time, toward the listener.

Philco combined its Model 4 shortwave converter with a Model 70 chassis to provide all-wave coverage. The result was Model 470. The Model 4 chassis in this model was modified, removing its separate power supply; power to both chassis was supplied from the upper Model 70 chassis, which was specially modified to handle the extra load.
