Overview
The Hammond Manufacturing 1750Z is a chassis-mount audio output transformer designed for guitar amplifier applications. It features a primary impedance of 10,000 ohms center-tapped and a secondary impedance of 8 ohms. The unit supports a power rating of 20 watts and operates within a frequency range of 70 Hz to 15 kHz. Constructed with wire lead terminations, this single-channel component belongs to the 1750 series and is manufactured by Hammond Manufacturing.
Feature Summary
- Designed specifically for high-power guitar amplifier output stages
- Provides center-tapped primary configuration for push-pull tube circuits
- Engineered for robust chassis mounting in professional audio equipment
Applications
- Guitar amplifier output stage construction
- Push-pull vacuum tube circuit implementation
- Professional audio equipment signal transformation
Procurement Notes
Verify the specific impedance configuration matches the target amplifier design requirements before procurement. Confirm that the 10k CT primary and 8-ohm secondary ratings align with the connected tubes and speaker load. Ensure the chassis mount style fits the intended enclosure layout. Cross-reference the manufacturer part number to avoid confusion with similar series variants.
Selection Notes
Select this component when a 20-watt power handling capacity is required for guitar amplification. The 10,000 ohm center-tapped primary is essential for matching specific output tube plate-to-plate impedances. Consider the physical dimensions and weight for chassis integration. This model is suitable for designs requiring a dedicated audio output transformer rather than general-purpose signal isolation.
Part Context
This component is part of the Hammond Manufacturing 1750 series, which includes various audio and signal transformers. Related models such as the 1750B offer different impedance ratios (5482 ohm primary) and lower power ratings (10 watts). The 1750Z specifically targets higher power applications compared to other members of the family.
Replacement Considerations
Direct substitutes within the same series include the 1750B, though it has different electrical specifications. Other Hammond models may share mechanical footprints but require verification of impedance and power ratings. No direct cross-manufacturer equivalents are confirmed in public documentation.
