Beltone "Super Largo" Transistor (Body) Hearing Aid

The Beltone "Super Largo" was produced by the Beltone Electronics Corp. of Chicago, IL in 1967.

The "Super Largo" measured 3” by 1 5/16” by ⅝” and weighed 2˝ oz with the battery. The "Super Largo" used 6 transistors in a push-pull (PP) circuit.

The case was brushed stainless steel front and back over a black plastic chassis—visible on all sides.
