Vacuum Tube Hearing Aids: 1921-1953

Rochester "Silver" Vacuum Tube Hearing Aid

The Rochester "Silver" vacuum-tube hearing aid was made by Rochester Acoustical Laboratories, Inc. of Rochester, MN in 1949. It contained 3 sub-miniature vacuum tubes.

The Rochester "Silver" model measured  3⅛" x 2⅛" x ⅞" thick and weighed 5¾ oz without the batteries.

An unusual feature of this hearing aid is that the case was sterling silver.
