Body Type Transistor Hearing Aids

Viennatone Model F Transistor (Body) Hearing Aid

The Viennatone Model F transistor hearing aid was made by Viennatone GES. M.D.H. in Vienna, Austria in 1958.

This 4-transistor hearing aid measured 3¼" x 2 7/16" x 13/16" (8.2 x 6.2 x 2.0 cm) and weighed 2½ oz. (72 g) without batteries.

Nowhere on this aid is the manufacturer's name or trade name shown.

Bottom view of the Viennatone Model F transistor hearing aid showing the battery compartment door opened revealing the two AA-sized batteries.

To open the battery compartment door, you unscrewed the plastic screw (center) enough so the door could swivel 90°.

There was no need to completely unscrew the battery compartment door as shown here.

Note the red + (right) and black - (left) showing the proper polarity of the batteries.

View of the battery compartment of the Viennatone Model F transistor hearing aid. This hearing aid was rather unusual in that it could use either 1 or 2 batteries depending how much power you needed.

If you only wanted to use 1 battery (left), then you used a dummy battery (right)  in the other slot as the two battery slots were hooked together in series.

View of the bottom of the Viennatone Model F transistor hearing aid showing the real battery (left) and the dummy battery (right).

This hearing aid used AA batteries such as this Eveready No. 1015E carbon-zinc battery.

Close-up view of the dummy battery of the Viennatone Model F transistor hearing aid. The dummy battery was a piece of plastic the same size as the real battery with a strip of metal that wrapped around both ends and one side to complete the circuit so the current from the real battery could flow.

The dummy batty (left) was exactly the same size as the real battery (right).
