Vacuum Tube Hearing Aids: 1921-1953

Paravox Model J 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.

It was one of a range of Paravox hearing aids of the time that had a very attractive brushed aluminum case with gold filigree microphone grills. The volume control wheel was at the top left and it had pocket clips on both sides.

Small for 1949, it measured 2⅞” by 2⅜” by ⅝” and weighed 4 oz. with batteries.

An unusual feature of the Paravox J is that the battery compartment cover slid off, rather than the usual hinged cover. Here it is shown half-opened.
