1750NA

Overview

The Hammond Manufacturing 1750NA is an audio output transformer designed for tube guitar amplifiers. It features a primary impedance of 6,000 ohms center-tapped and secondary options of 8 or 16 ohms. The unit supports power ratings of 30W and 60W. Operating frequency ranges from 70 Hz to 15 kHz. Construction utilizes wire lead termination and chassis mounting. The component belongs to the 1750 series and is intended for push-pull tube output applications.

Feature Summary

Designed as a drop-in replacement for original factory units with similar physical dimensions
Supports dual secondary impedance configurations for versatile amplifier matching
Constructed for high-power tube output stages in guitar amplification systems

Applications

Tube guitar amplifier output stages
Push-pull tube circuit integration
Audio signal transformation in vintage-style equipment

Procurement Notes

Verify the specific secondary impedance requirement (8 ohm or 16 ohm) against the target amplifier design before ordering. Confirm that the required power handling capacity aligns with either the 30W or 60W rating specified for this model. Ensure chassis mounting provisions are compatible with the existing enclosure structure. Cross-reference the primary impedance specification to guarantee proper tube load matching.

Selection Notes

Select this model when a direct physical replacement for legacy amplifier designs is required. Choose based on the necessary secondary impedance configuration to match speaker loads accurately. Consider the power rating requirements to ensure adequate headroom for the intended application. Verify compatibility with existing chassis mounting standards and wire lead termination methods.

Part Context

This component is part of the Hammond 1750 series, which specializes in audio and signal transformers for tube applications. The series includes various models tailored for different primary impedances and power levels. These transformers are engineered to maintain historical accuracy while providing reliable performance in modern reproductions of classic audio equipment.

Replacement Considerations

This model is explicitly designed as a drop-in replacement for original factory units where possible. Verify physical dimensions and mounting hole patterns to ensure compatibility with existing chassis layouts.
