1750V

Overview

The Hammond Manufacturing 1750V is an audio output transformer designed for tube guitar amplifier applications. It features a push-pull configuration with wire lead termination. The primary side impedance is 4,150 ohms center-tapped (CT), and the secondary side impedance is 8 ohms. The unit operates within a frequency range of 70 Hz to 15 kHz. It is constructed for base mounting and belongs to the 1750 series.

Feature Summary

Designed specifically for tube guitar amplifier output stages
Push-pull circuit topology implementation
Wire lead termination style for direct integration

Applications

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

Procurement Notes

Verify the specific impedance configuration against the target amplifier design requirements. Confirm that the wire lead termination method aligns with the existing chassis wiring layout. Ensure the physical dimensions accommodate the available mounting space within the amplifier enclosure. Cross-reference the center-tapped primary specification with the power tube plate requirements.

Selection Notes

Select this component when a 4,150 CT primary impedance is required for the specific tube type used in the amplifier circuit. Consider the 8-ohm secondary match for the connected speaker load. Evaluate the 70 Hz to 15 kHz frequency response suitability for the desired tonal characteristics. Compare against other 1750 series variants if different impedance ratios are needed.

Part Context

This transformer is part of the Hammond 1750 series, which provides various impedance options for tube audio applications. It serves as a critical interface between the vacuum tubes and the speaker, ensuring proper power transfer and impedance matching. The series is known for reliability in high-voltage audio environments.

Replacement Considerations

Direct substitutes include other Hammond 1750 series models with identical 4,150 CT primary and 8-ohm secondary specifications. Verify mechanical mounting compatibility and lead length when considering alternative manufacturers.
