Overview
The Hammond Manufacturing 1750Y is a single-channel audio output transformer designed for tube application power circuits. It features wire lead termination and operates within a frequency range of 70 Hz to 15 kHz. The primary winding impedance is 6,200 ohms center-tapped, while the secondary winding provides an 8-ohm impedance. The unit has a power rating of 15 watts and utilizes a push-pull configuration. It weighs approximately 1.814 kg.
Feature Summary
- Designed specifically for tube amplifier output stages
- Push-pull topology with center-tapped primary winding
- Wire lead termination for direct circuit integration
Applications
- Guitar amplifier output stages
- Tube-based audio signal processing
- Hi-fi amplifier construction
Procurement Notes
Verify that the specific 1750Y part number matches the required 6,200 ohm center-tapped primary impedance and 8 ohm secondary specification. Confirm wire lead orientation and physical mounting requirements against the dimensional drawing. Ensure compatibility with the target tube amplifier's plate voltage and current draw limits before finalizing procurement.
Selection Notes
Select this component when a 15-watt push-pull output transformer with a 6.2k CT primary is required. Compare against similar models like the 1750E if different primary impedances are needed. Consider the significant weight and wire lead format for mechanical design. Validate that the 70 Hz to 15 kHz frequency response meets the audio fidelity requirements of the specific application.
Part Context
This component belongs to the Hammond 1750 series of audio and signal transformers. It is categorized under tube application power transformers. The series includes various impedance configurations tailored for different vacuum tube output stages. This specific model represents one variant within the broader family of Hammond audio transformers.
Replacement Considerations
The Hammond 1750E serves as a related alternative within the same series, offering a different primary impedance configuration. Verify electrical compatibility and physical dimensions before substituting.
