Body Type Transistor Hearing Aids

Beclere Model 2500 "Deluxe" Transistor (Body) Hearing Aid

This Beclere Model 2500 "Deluxe" transistor body hearing aid was made by the Beclere Co., Ltd. of Oxford, UK in 1960.

The Model 2500 "Deluxe" measured 2 9/16" x 1½" x 9/16" (6.5 x 3.8 x 1.5 cm) and weighed 1.4 oz (40 g) without the battery. It had a dark reddish-brown front and chrome back. This hearing aid used four transistors in a push-pull amplifier.

This is the only hearing aid I've come across that used the letter "L" (loop) rather than "T" (t-coil) to describe the function of this switch. (The t-coil is mounted right by this switch.)
