Overview
The Hammond Manufacturing 1750S is an audio and signal transformer designed for tube application power transformers. It functions as an output transformer for guitar amplifiers with a push-pull configuration. The unit features wire lead termination and operates within a frequency range of 70 Hz to 15 kHz. Key electrical parameters include a primary impedance of 5,100 ohms center-tapped, a secondary impedance of 8 ohms, and a single channel design. The power rating is specified at 25 watts.
Feature Summary
- Designed specifically for tube application power transformers in guitar amplifier circuits
- Supports push-pull output configurations for audio signal transformation
- Utilizes wire lead termination for direct circuit integration
Applications
- Guitar amplifier output stages
- Tube-based audio equipment reconstruction
- Push-pull amplifier circuit implementation
Procurement Notes
Verify the specific impedance requirements against the target amplifier circuit before procurement. Confirm that the 5,100 ohm center-tapped primary and 8 ohm secondary match the existing tube plate loads and speaker impedance. Ensure the 25-watt power rating exceeds the amplifier's maximum output demand to prevent thermal failure. Check physical dimensions and lead lengths for compatibility with the chassis layout.
Selection Notes
Select this component when a 25-watt push-pull output transformer is required for tube guitar amplifiers. The 5,100 ohm center-tapped primary is suitable for specific tube types such as EL34 or 6L6GC depending on biasing. The 8-ohm secondary matches standard speaker impedances. Consider the 1750 series variants if different power ratings or impedance ratios are needed for alternative tube configurations.
Part Context
The 1750S belongs to the Hammond 1750 series of tube guitar amplifier output transformers. This series provides various impedance and power options for different amplifier designs. The 1750S specifically targets mid-power applications requiring a 5,100 ohm center-tapped primary. It is part of a broader lineup including models like the 1750B and 1750Y for different circuit requirements.
Replacement Considerations
Direct substitutes within the same series include the 1750B (10W, 5482 ohm) and 1750Y (15W, 6200 ohm). Verify that the replacement matches the primary impedance, secondary impedance, and power handling capabilities of the original design.
