Zenith "Crusader" [Mod I] Transistor (Body) Hearing Aid
The Zenith "Crusader" [Mod I] Transistor Hearing Aid was manufactured by the
Hearing Aid Division of the Zenith Radio Corp. beginning in August, 1958. It was an
4-transistor aid.
The difference between the Zenith "Crusader" (previous page) and the
"Crusader [Mod I] is that the Mod I had an external clip-in
microphone like the "Crusader X". (not shown).
The Zenith "Crusader" [Mod I] measured 2" x 1⅜" x ⅝" thick
(1" thick with plug-in microphone), and weighed 1˝ oz. with battery. The case was
gold-colored anodized aluminum.
The picture at the right shows the Zenith "Crusader" [Mod
I] with the
microphone (right) attached to the external microphone cord.
The "Crusader" [Mod I] had the word "ZENITH" centered across
the bottom (as shown), exactly like the original "Crusader" had.

Front view of the Zenith "Crusader" [Mod I] showing the unusual clip-on
microphone. (The "Crusader" [Mod I] did not have a built-in microphone.) This
way the microphone could be attached to the hearing aid (as shown) or
removed and attached to the clothing while the hearing aid itself was
"hidden" in a pocket.
The microphone ports are the two holes, one on each side of the
Zenith crest. |
