1615

Overview

The Hammond Manufacturing 1615 is a push-pull audiophile tube output transformer designed for audio applications. It features a primary winding with a center tap at 5,000 ohms and a secondary winding offering selectable impedances of 4, 8, and 16 ohms. The unit has a power rating of 15 watts and supports a secondary current of 100 mA. Constructed for high-fidelity performance, it utilizes a single primary and dual secondary configuration to facilitate balanced audio signal transmission in tube-based amplifier circuits.

Feature Summary

Push-pull topology optimized for audiophile tube output stages
Dual secondary windings providing selectable impedance taps
Center-tapped primary winding design for balanced operation

Applications

High-fidelity vacuum tube audio amplifiers
Push-pull tube output stage coupling
Audiophile speaker driver interfacing

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing revisions may occur. Confirm that the physical mounting style matches the intended chassis layout. Ensure the thermal environment supports continuous operation at the rated power level without exceeding temperature limits defined by the insulation class.

Selection Notes

Select this component based on the required primary impedance matching the tube plate-to-plate load and the secondary impedance matching the speaker cabinet. Verify that the 15-watt power rating exceeds the amplifier's maximum output requirements. Consider the physical dimensions and mounting hardware compatibility with the existing enclosure design.

Part Context

This part belongs to Hammond Manufacturing's line of audio transformers, specifically targeting the niche market of high-end tube audio equipment. Unlike general-purpose industrial transformers, these units are engineered for low distortion and precise frequency response characteristics essential for musical reproduction.
