Body Type Transistor Hearing Aids

Maico Model AB Transistor (Body) Hearing Aid

The Maico Model AB body-style hearing aid was manufactured by Maico Electronics, Inc. of Minneapolis, MN in 1956.  The name "Maico" was derived from the initials of the Medical Acoustic Instrument Company.

The Model AB was a 3-transistor economy version of the Model W hearing aid. The front of the case was anodized aluminum, and the back was black plastic. It measured 2½" x 1¾" x ¾" thick.
