Overview
The Hammond Manufacturing 1750TC is a tube application power transformer designed for audio signal processing. It features an 8,500-ohm center-tapped primary impedance and an 8-ohm secondary impedance. The unit supports a power rating of 15 watts with a frequency range spanning from 70 Hz to 15 kHz. It utilizes wire lead termination and is intended for chassis mounting applications.
Feature Summary
- Designed specifically for tube output push-pull amplifier circuits
- Provides precise impedance matching between high-voltage primary and low-resistance secondary windings
- Ensures stable audio signal transmission within the specified frequency bandwidth
Applications
- Tube guitar amplifier output stages
- Hi-fi audio equipment push-pull configurations
- Professional audio signal transformers
Procurement Notes
Verify that the specific part number matches the required 8kCT primary and 8 ohm secondary configuration. Confirm chassis mounting compatibility and wire lead orientation prior to integration. Ensure the 15W power rating aligns with the circuit design requirements to prevent thermal overload or performance degradation in the final assembly.
Selection Notes
Select this component when a dedicated output transformer for tube-based push-pull architectures is required. The 8kCT primary specification suits common vacuum tube pentodes requiring high plate-to-plate impedance. Consider the physical dimensions and weight for enclosure space planning. This model is distinct from other series variants with different impedance ratios.
Part Context
This component belongs to the Hammond 1750 series of audio and signal transformers. It shares the same form factor and mounting style as models like the 1750E but differs in electrical specifications. The series is recognized for use in vintage and modern tube amplifier designs requiring reliable isolation and impedance transformation.
Replacement Considerations
Direct substitutes include the Hammond 1750E, which shares identical 8kCT primary and 8 ohm secondary ratings. Verify mechanical fit and lead length compatibility before substitution.
