Vacuum Tube Hearing Aids: 1921-1953

Rion Model H-525 "Rionet" Vacuum Tube Hearing Aid

The Rion Model H-525 "Rionet" vacuum-tube hearing aid was made by the Rion Co. Ltd in Tokyo, Japan in 1954.

The Rion Model H-525 "Rionet" model measured  3⅝" x 2¼" x ¾" thick and weighed 5 oz without the batteries.

The Rion Co. kept on making vacuum tube hearing aids until 1956, although the other hearing aid manufacturers quit making them in 1953.
