Vintage ITT Terryphone Wall-Mount Intercom Station – Model AW3 (Chassis 1704) For Sale

Vintage ITT Terryphone Wall-Mount Intercom Station – Model AW3 (Chassis 1704)

Product Overview

Up for sale is a rare piece of industrial telecommunications history: a vintage ITT Terryphone Wall-Mount Intercom Station (Model AW3, Catalog Chassis No. 1704). Manufactured during the mid-to-late 20th century, these heavy-duty internal communication stations were built to survive rugged warehouse, factory, and commercial office environments.

Operating on a unique "Page and Reply" system, a user would lift the heavy handset, press a page button to broadcast across a facility, and another user could pick up a nearby station to establish a private intercom line. This unit features a robust industrial metal housing, a built-in heavy-duty loudspeaker cone behind the classic front grille, and dual top-mounted indicator light housings.

Item Condition & Technical Bench Notes

• Cosmetic Condition: Good vintage condition with expected light wear, minor scuffs, and character from years of commercial service. Internal chassis and factory wiring harnesses are fully intact, remarkably clean, and free of heavy corrosion.

• Bench Testing Actions: The internal paging amplifier circuit has been energized on a test bench using a standard 24V DC power supply input.

• Functional Notes: When powered up across the factory G/R/W terminals, the internal paging circuit responds actively, producing a distinct, healthy audio chirp/popping tone directly from the front loudspeaker. This confirms that the internal audio output transformer and the speaker cone are functioning.

• Signaling/Lights: Main terminal power routes cleanly to the logic board. The top indicator lamp circuits are physically intact, though the vintage incandescent bulbs under the top plastic indicator caps may need basic cleaning or replacement to fully illuminate.

• Ideal For: Vintage industrial electronics collectors, ham radio enthusiasts, historical prop houses, or anyone looking to restore a classic mid-century internal communications network.
