View of the bottom left corner of the Audivox Model 74-3 "Petite" transistor body hearing aid showing
not one, but two, receiver cord jacks. This uncommon arrangement allowed
a person to wear a receiver in each ear at the same time. The two pins
on the receiver cord plug were of the same size so you could plug it in
any way you wanted to.
