Body Type Transistor Hearing Aids

Beltone "Forte" Transistor (Body) Hearing Aid

The Beltone "Forte" was produced by the Beltone Electronics Corp. of Chicago, IL in 1973.

The "Forte" measured 2¼” by 1⅝” by ¾” and weighed 2½ oz with the battery. The "Forte" used 8 transistors in a push-pull (PP) circuit.

The case was black metal (although these pictures make it look dark brown).

An interesting and perhaps unique thing about the Forte is that the t-coil is actually contained within the pocket clip on the front of the hearing aid case.

Top view of the Beltone "Forte" showing four controls—two at each corner with the microphone grill in the center. The two-position switch (top left) is the on-off switch. The volume control wheel (marked 0 - 7) is at the bottom left. The tone control wheel (marked 0 - 7) is in the top right corner. The microphone/t-coil switch is in the bottom right corner. It is marked "T" (t-coil), "B" (both microphone and t-coil at the same time), and "M" (microphone).

Right side view of the "Forte" showing the 2-hole receiver cord jack (center). The holes were not the same size so the plug could only be plugged in the correct way.
