Toshiba Model THA-1001 Transistor (Body) Hearing Aid
The Toshiba Model THA-1001 transistor body hearing aid was
manufactured by the Tokyo Shibaura Electric Co., Ltd. in Tokyo, Japan in
1961 and was distributed under the "Toshiba" trade name by Transistor World
Corporation of New York, NY.
This 4-transistor hearing aid measured 2 15/16" x 2" x 11/16" (7.5 x 5.0 x 1.7 cm) and
weighed 2.4 oz (68 g) without the battery.
Back in 1961 this hearing aid only cost $29.88 as shown in this
coupon.

the Toshiba name (top) and below it the brown triangular-shaped
microphone grill. The large "V"-shaped wire pocket clip is in the
center. Note that this microphone grill is brown (in contrast to the
model THA-1002 which had a green grill).

top left corner the letters "L" (low) and "H" (high) for
indicating the tone setting.
Near the bottom are stamped the words "Toshiba" (in script), and
below that the model number (THA-1001), and below that the name of the
manufacturer (Tokyo Shibaura Electric Co., Ltd.) and "Japan". |

Front view of the receiver cord plug of the Toshiba Model THA-1001
transistor hearing aid. Note that the left pin is larger in diameter
than the right pin in order to preserve correct polarity. Also note that
the pins are offset to the right so the pins wouldn't fit into the jack
if you tried to put them in backwards. On the front of the plug is the
name "Toshiba" in script and below that "Japan". |

Side view of the receiver of the Toshiba Model THA-1001 transistor hearing aid
showing the stock ear mold attached. This receiver was smaller than most
receivers at the time at ⅝" in diameter (1.6 cm). It looked like a
transistor radio ear bud of that era. In contrast the model THA-1002
had a "normal-sized" receiver that was 13/16" (2.1 cm) in diameter.
