Body Type Transistor Hearing Aids

Philco Mark I "Audipage" Transistor (Body) Hearing Aid

The Philco Mark I "Audipage" was made by Philco of Philadelphia, PA. The Mark I "Audipage" was first produced in 1955.

This hearing aid was quite small for the time and measured 1¾" x 1⅝" x ½" and weighed 1¼ oz. without the battery.

It had a chrome case and contained 3 transistors. The t-coil sat behind the 4 "star bursts" grill (lower left front).

The Philco Mark I "Audipage" was unique among hearing aids of its time in that it had no microphone. Instead, it had a t-coil where the microphone normally would have been. Thus, the "Audipage was used in rooms that were looped with an magnetic induction loop system. In this respect, the "Audipage" is really an assistive device rather than a hearing aid.

The picture at the right shows the inside view of the Philco Mark I "Audipage" with the front cover removed. The t-coil is wrapped in masking tape in the bottom left quadrant.

The Philco Mark I "Audipage" had a somewhat unusual plug for the receiver cord. Instead of the two pin plug that was common (and used at the receiver end), it used what looks like a standard audio plug, but it is slightly bigger—just a bit over ⅛" in diameter.

Externally, the "Audipage" was identical to the Philco Mark I except that it had the word "Audipage" engraved in the center of the case.

The battery door on the Philco Mark I  "Audipage" swung up and to the right from the bottom right corner. This hearing aid used a 625 battery.

The clip across the front of the hearing aid could be used as a tie clip with the hearing aid itself hidden under the tie.
