Vacuum Tube Hearing Aids: 1921-1953

Paravox Model J (Tiny Myte) Vacuum Tube Hearing Aid

The Paravox Hearing Aid Company of Cleveland, Ohio manufactured the Paravox Model J (Tiny-Myte) vacuum tube hearing aid in 1949.

The Model J was one of the Paravox hearing aids that had attractive brushed aluminum cases with gold filigree microphone grills.

Small for 1949, it measured 2⅞” by 2 7/16” by 11/16” (7.4 x 6.2 x 1.7 cm) and weighed 2.2 oz. (62 g) without the batteries.
