Overview
The Hammond Manufacturing 1750YA is a chassis-mount audio transformer designed for tube amplifier output stages. It features a push-pull configuration with a primary impedance of 6,200 ohms center-tapped and a secondary impedance of 8 ohms. The unit supports a power rating of 15W and operates within a frequency range of 70Hz to 15kHz. It utilizes wire lead termination and is constructed for single-channel applications.
Feature Summary
- Engineered specifically for tube amplifier output stages in audiophile and ultra-linear configurations
- Supports push-pull circuit topology for balanced signal processing
- Features chassis mounting design with wire lead termination for secure integration
Applications
- Tube guitar amplifier output stages
- Audiophile audio equipment construction
- Ultra-linear amplifier designs
Procurement Notes
Verify the specific part number suffix against official Hammond Manufacturing documentation to confirm impedance values and power ratings. Ensure compatibility with existing chassis dimensions and wiring requirements before procurement. Cross-reference datasheets for precise electrical characteristics to avoid mismatches in high-fidelity audio circuits.
Selection Notes
Select this component when designing tube-based amplifiers requiring a 6.2kCT primary impedance. Consider the 15W power handling capacity and 70Hz-15kHz frequency response for musical instrument or hi-fi applications. Evaluate physical mounting constraints as it requires chassis installation rather than PCB mounting.
Part Context
This model belongs to the Hammond 1750 series of audio transformers. It shares the series designation with variants like 1750E and 1750Y but differs in primary impedance specifications. The series is recognized for use in vintage-style and modern tube amplifier builds requiring reliable signal transformation.
Replacement Considerations
Direct substitutes include models such as 1750Y and 1750KA from the same manufacturer. Verify that alternative parts match the 6,200 ohm center-tapped primary impedance and 8 ohm secondary impedance to maintain circuit integrity.
