Fidelity Model F-360 Transistor (Body) Hearing Aid

The Fidelity Model F-360 body style transistor hearing aid was manufactured by Viennatone in Austria and distributed in North America under the trade name of "Fidelity" by Fidelity Electronics Ltd of Miami, Florida.

The Model F-360 was was probably a 3-transistor model and contained a t-coil. It was made in 1967. The equivalent Viennatone model was probably the X3 model.

The Fidelity model F-360 was the basic version of the model F-364 which had more features.

This hearing aid measured 2 7/16" high x 1 13/16" wide x 11/16" thick. (6.2 x 4.6 x 1.7 cm) and weighed 2 oz. (56 g) without the battery.
