Zenith Model 50-R Transistor (Body) Hearing Aid
The Zenith Model 50-R Transistor Hearing Aid was manufactured by the
Hearing Aid Division of the Zenith Radio Corp. in 1957. It was an 4-transistor aid.
The Zenith Model 50-R measured 2⅝" x 1¾" x
⅝" thick, and weighed 2 oz. with battery. The aluminum case was
unusual in that it was colored black rather than the light silver or
gold colored cases usually used by Zenith (and other manufacturers) at
this time.
The vertical rectangular microphone grill was in the front center of the case.
Notice that the pocket clip ran across the microphone grill near its
bottom.
