Vacuum Tube Hearing Aids: 1921-1953

Beltone Mono-pac Model R "Rhapsody" Vacuum Tube Hearing Aid

The Beltone Mono-pac Model R "Rhapsody" vacuum tube one-piece hearing aid was  produced by the Beltone Electronics Corp. of Chicago, IL in 1952.

 It measured 3⅛” by 1¾” by ⅞” and weighed 4½ oz including the batteries. It used 3 vacuum tubes.

The case was chrome front and back over a black (or wine-colored) plastic chassis—visible on all sides. Pocket clip is on the front in the center.

The microphone grill (top right corner) is in the shape of a lyre—the same design as used on the Model L.

Not all the Beltone Model R "Rhapsody" hearing aids had t-coils. This one didn't.

The Beltone Rhapsody was still selling for $215.00 in July of 1953 at the time when vacuum tube aids had just become obsolete.

View of the battery compartment of the Beltone Mono-pac Model L showing the batteries in place. The "A" battery (center) is an RM-1 1.4 volt mercury battery, while the "B" battery is a 30 volt No. 506 E.

Note that in the above invoice, this hearing aid came with only one No. 506 E "B" battery, but with 8 RM-1 "A" batteries because the "A" batteries didn't last near as long as the "B" battery.

The battery compartment door is hinged at the top and swings upward.

The Model R is much the same as the Model L except for the larger battery compartment which necessitated a longer case. This 30 volt battery would produce more power than the 15 volt battery used in the Model L—so the Model R is likely a higher powered version of the Model L.
