War Model

Because they are low on the priority list for critical materials, TV manufacturers have been desperately searching for metallic substitutes or short cuts. RCA is contributing a 90% saving in the use of cobalt by developing an electrostatic picture tube and redesigning loudspeakers. In Washington last week, enterprising Philco became the first manufacturer to demonstrate a new-model wartime TV set that saves 26% in copper, 51% in ferrite, 58% in silicon steel, 68% in aluminum, 15% in nickel, and eliminates entirely the use of the critical alloy, Alnico No. 5.

Philco's set, scheduled for mass production by summer, performs as well as the pre-Korea models and will cost "approximately" the same. One possible drawback: the substitute materials may cut down on the life expectancy of the new sets. More serious for U.S. set owners who have to replace old parts: the new substitute materials may not always work in old-model sets.
