Lafayette Model TR-7 (F-360) Transistor (Body) Hearing Aid
The Lafayette Model TR-7 (F-360) transistor body hearing aid was made for
Lafayette Radio Electronics of Syosset, NY by Conny Industrial Co. Ltd, Tokyo, Japan in 1959.
Note that the Model TR-7 was sold by Conny under their own name, and by
Magnatone and Lafayette under their respective names.
This 4-transistor hearing aid measured 2⅝" high x 1¾" wide x 11/16"
thick (6.7 x 4.5 x 1.8 cm) and weighed 1.7 oz. (48 g) without the
battery.

gold or silver colored.
