Overview

The Hammond Manufacturing 118944 is an interstage audio transformer designed as a replacement for the RCA Radiola III-A. It features a primary winding with 4000 turns and a secondary center-tapped winding with 12000 turns. The unit utilizes solder lugs for electrical connections and measures 52.3 mm by 42.9 mm by 35.1 mm.

Feature Summary

Designed specifically as a replacement component for vintage RCA Radiola III-A equipment
Features a center-tapped secondary winding configuration for audio signal coupling

Applications

Restoration of RCA Radiola III-A radio sets
Vintage audio equipment repair involving interstage coupling
Historical radio reconstruction projects

Procurement Notes

Verify that the replacement matches the original physical dimensions and terminal configuration to ensure compatibility with vintage chassis layouts. Confirm that the solder lug style aligns with existing circuit board or wiring harness requirements before installation in historical audio systems.

Selection Notes

Select this model only when servicing RCA Radiola III-A units requiring specific turn ratios and center-tapped secondary outputs. Ensure the application does not require different impedance matching characteristics than those provided by the 4000-to-12000-turn design.

Part Context

This component belongs to Hammond Manufacturing's line of specialized audio transformers intended for heritage electronics restoration. It serves a niche market focused on maintaining the operational integrity of early vacuum tube radio receivers.
