Vacuum Tube Hearing Aids: 1921-1953

Automatic "Super Power" Vacuum Tube Hearing Aid

The "Automatic" vacuum tube hearing aid was manufactured by an unnamed US company around 1947 (unless "Automatic" was the name of the company).

This attractive hearing aid sported a shiny aluminum front with a black metal back.

Without the batteries, it weighed 3.8 oz. (108 g). It measured 5⅛" x 2˝" x ⅞" thick (13.0 x 6.3 x 2.2 cm).
