146B

Overview

The Hammond Manufacturing 146B is an audio transformer designed for chassis mounting. It features a primary impedance of 48CT ohms and a secondary impedance of 3.2 ohms. The device operates within a frequency range of 150Hz to 15kHz with a frequency response of ±1dB. Primary DC resistance is 4.4 ohms, while secondary DC resistance is 700 milliohms. Power handling capacity is rated at 700mW. Physical dimensions are 1.630 inches in length, 0.880 inches in width, and a maximum installation height of 0.810 inches.

Feature Summary

Designed for general-purpose use and replacement in push-pull tube output circuits
Utilizes high-quality magnetics suitable for tube applications such as hi-fi systems

Applications

Push-pull tube output circuits
Hi-fi audio systems
Chassis-mounted audio equipment

Procurement Notes

Verify the specific part number against official Hammond Manufacturing documentation to confirm impedance values and physical specifications. Ensure compatibility with existing chassis mounting requirements and circuit design parameters before procurement. Cross-reference datasheets for accurate electrical characteristics.

Selection Notes

Select this component for applications requiring a 48CT primary to 3.2 secondary impedance ratio in tube-based audio circuits. Consider the chassis mount style and physical dimensions for enclosure integration. Verify that the 700mW power rating meets the operational requirements of the target audio stage.

Part Context

This component belongs to the Hammond Manufacturing 146 series of audio transformers. These units are engineered for robust performance in analog audio signal paths. The series supports various impedance configurations tailored for different tube amplifier topologies, providing reliable magnetic coupling for audio frequencies.

Replacement Considerations

The 146E is a related model in the same series but features different impedance specifications (100CT primary, 8 ohm secondary). Verify impedance matching requirements when considering substitutes to ensure circuit compatibility.
