Vacuum Tube Hearing Aids: 1921-1953

Western Electric Model 66 "Super" Vacuum Tube Hearing Aid

The Western Electric Model 66 "Super" hearing aid was made by the Western Electric Co. of Kearny, N.J. in 1947.

It was a 1-piece hearing aid and had a crystal microphone. The dimensions of the Model 66 was 5" x 2˝" x 1". It weighed 7˝ oz. without the batteries.

The Model 66 came in two colors. Shown here is the two-tone light gray/dark gray version. It also came in a beige version.

Apparently there was an optional external 30 volt battery pack.

The tone control has 3 positions. The 3-dot position (shown) gives full range of tones. The 2-dot position moderately suppresses low-frequency sounds, and the 1-dot position gives maximum suppression of low frequency sounds.
