117F8

Overview

The Hammond Manufacturing 117F8 is an audio signal transformer designed for line matching applications. It features a primary impedance of 8 ohms and a secondary impedance of 8 ohms, supporting a power rating of 8 watts. The unit operates within a frequency range of 100 Hz to 9 kHz. It utilizes chassis mounting with quick connect termination style. The physical dimensions are approximately 60.5 mm in length, 35.1 mm in width, and 35.1 mm in height, with a weight of roughly 226.8 grams.

Feature Summary

• Designed for general-purpose use and replacement in push-pull tube output circuits
• Features high-quality magnetics suitable for tube applications such as hi-fi systems

Applications

• Push-pull tube output circuit replacement
• Hi-fi system integration
• Line matching in audio signal paths

Procurement Notes

Verify the specific impedance configuration required for your application, as the 117 series includes variants with different primary and secondary impedances. Confirm that the quick connect termination style matches your existing wiring harness or PCB layout. Ensure the chassis mounting footprint aligns with your enclosure design constraints before finalizing procurement.

Selection Notes

Select this model when a direct replacement for tube-based audio equipment is needed. The 8-ohm to 8-ohm configuration is distinct from other 117 series variants like the 117E8 which may have different impedance ratios. Consider the physical size and mounting requirements to ensure compatibility with the target chassis space.

Part Context

The 117F8 belongs to the Hammond 117 series of audio and signal transformers. This series is characterized by its use in professional and consumer audio equipment, particularly those utilizing vacuum tube technology. The component serves as a critical interface for impedance matching between amplifier stages and speakers or lines.
