Zenith Model A3AN-B3AN "Radionic" Vacuum Tube Hearing Aid
The Zenith Model A3AN-B3AN "Radionic" vacuum tube hearing aid was
manufactured by the Hearing Aid Division of the Zenith Radio Corporation
of Chicago, IL beginning in 1945.
Apart from the pink plastic case (instead of the black plastic case of
the Model A3A-B3A), and the "N" in the Model number, this hearing aid
appears to be identical to the Model A3A-B3A. Therefore, press the back
button to see all the pictures and details as shown on the
previously-listed A3A-B3A model.
Note that instead of a receiver, this picture shows the bone
conduction transducer (right). |
