Overview
The Hammond Manufacturing 1750WA is a tube output transformer designed for guitar amplifiers. It features a primary impedance of 2,000 ohms center-tapped and secondary impedances of 2, 4, and 8 ohms. The unit supports a power rating of 100 watts with a frequency range of 70 Hz to 15 kHz. It utilizes wire lead termination and chassis mounting.
Feature Summary
- Designed specifically for high-power tube guitar amplifier output stages
- Provides multiple secondary impedance options (2, 4, and 8 ohms) for flexible speaker matching
- Supports 100-watt power handling capacity for robust audio signal transmission
Applications
- High-power tube guitar amplifier construction
- Audio output stage replacement in vintage or custom amplifiers
- Speaker impedance matching in professional audio equipment
Procurement Notes
Verify the specific application requirements against the 100W power rating and 2kCT primary impedance before procurement. Ensure the chassis mounting style and wire lead termination are compatible with the existing amplifier design. Confirm that the multi-tap secondary configuration matches the available speaker cabinet impedances.
Selection Notes
Select this component when a 100-watt output transformer is required for tube-based guitar amplification systems. The 2,000-ohm center-tapped primary is suitable for specific tube configurations such as EL34 or similar power tubes commonly used in high-gain amplifiers. The inclusion of 2, 4, and 8-ohm secondaries allows for versatile speaker load connections.
Part Context
This model belongs to the Hammond Manufacturing 1750 series of audio and signal transformers. This series includes various output transformers tailored for different power levels and impedance requirements in tube amplifier applications. The 1750WA represents the higher power variant within this family, distinguished by its 100-watt rating compared to lower-wattage counterparts like the 1750B or 1750KA.
