1750BB

Overview

The Hammond Manufacturing 1750BB is an audio output transformer designed for tube amplifier applications. It features a primary impedance of 4,800 ohms and secondary options of 4, 8, or 16 ohms. The unit supports a power rating of 10 watts with a frequency range of 70 Hz to 15 kHz. Constructed with wire leads, it serves as a replacement component in push-pull tube output circuits.

Feature Summary

Designed for general-purpose use and replacement in push-pull tube output circuits
Supports multiple secondary impedance configurations including 4, 8, and 16 ohms
Utilizes wire lead termination for direct circuit integration

Applications

Push-pull tube audio output circuits
Guitar amplifier reconstruction
Vintage audio equipment restoration

Procurement Notes

Verify the specific secondary impedance configuration required (4, 8, or 16 ohms) before ordering, as the model number may not explicitly denote the selected variant in all listings. Confirm that the primary impedance matches the existing circuit design at 4,800 ohms. Ensure the 10-watt power rating aligns with the amplifier's output stage requirements to prevent thermal overload or performance degradation during operation.

Selection Notes

Select this component when replacing failed output transformers in tube amplifiers requiring a 4,800-ohm primary impedance. It is suitable for designs utilizing push-pull tube configurations. Consider the physical dimensions and weight if space constraints exist within the chassis. Verify compatibility with the existing speaker load impedance by choosing the correct secondary variant from the available options.

Part Context

This component belongs to the Hammond 1750 series of audio and signal transformers. The series includes various models tailored for different tube amplifier topologies and power levels. The 1750BB specifically addresses mid-power applications common in guitar and hi-fi tube amplifiers, offering reliable performance for standard push-pull architectures.
