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.

Top right view of the Beclere Model 2500 "Deluxe" transistor body hearing aid showing the
0 - 5 volume control wheel and below that the 3-position switch.
Presumably it is the on-off switch (shown in the off position), but why
the two "on" positions is unknown. |

Close-up view or the right side of the Beclere Model 2500 "Deluxe"
transistor body hearing aid showing the M-L switch in the "L" position.
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.)
