Beltone Mono-pac Model C "Concerto"  Transistor (Body) Hearing Aid

The Beltone Mono-pac Model C "Concerto" was produced by the Beltone Electronics Corp. of Chicago, IL in 1953.

It measured 2⅞” by 2” by ⅝” and weighed 3 oz including the battery. It used 3 transistors.

The case was chrome front and back over a plastic chassis—visible on all sides. Pocket clips are on the front near each side.

The square microphone grill (top right) incorporates a lyre design.
