Overview
The Hammond Manufacturing 1750FA is an audio output transformer designed for tube amplifier applications. It features a primary impedance of 7,000 C.T. Ohms and secondary impedances of 8 and 16 Ohms. The unit has a power rating of 15 W and operates within a frequency range of 70 Hz to 15 kHz. It utilizes wire lead termination and is intended for chassis mounting in push-pull tube output circuits.
Feature Summary
- Designed specifically for tube output push-pull amplifier configurations
- Provides dual secondary impedance options of 8 and 16 Ohms
- Features a center-tapped primary winding with 7,000 Ohm impedance
- Utilizes wire lead termination for direct circuit integration
Applications
- Tube guitar amplifier output stages
- Hi-Fi audio amplifier construction
- Vintage audio equipment restoration
- Push-pull tube circuit implementation
Procurement Notes
Verify the specific datasheet version for the 1750FA model to confirm exact dimensional tolerances and electrical characteristics. Ensure compatibility with existing chassis mounting requirements and wiring harness specifications before procurement. Cross-reference manufacturer documentation for any updates regarding RoHS compliance or material composition changes.
Selection Notes
Select this component when a 15 W power rating and 7,000 C.T. primary impedance are required for tube output stages. The dual secondary taps allow flexibility for connecting 8 or 16 Ohm speaker loads. Consider physical dimensions and weight constraints during design integration to ensure proper chassis fitment and thermal management.
Part Context
This component belongs to the Hammond Manufacturing 1750 series of audio and signal transformers. The series includes various models differentiated by primary impedance, power rating, and secondary configuration. These units are standard components in vacuum tube electronics, providing necessary impedance matching between tube plates and speaker loads.
Replacement Considerations
Direct substitutes within the same series include models such as 1750E and 1750B, though these differ in primary impedance and power ratings. Verify that alternative parts match the 7,000 C.T. primary requirement and 15 W capacity to maintain circuit performance.
