126C

Overview

The Hammond Manufacturing 126C is an audio transformer designed for tube driver interstage applications in single-ended tube amplifiers. It features a power rating of 4W and an inductance of 106 Henrys. The primary impedance is 10k Ohms, and the secondary impedance is also 10k Ohms. The frequency response ranges from 20Hz to 20kHz. The unit utilizes a chassis mount installation style.

Feature Summary

Designed specifically for tube driver interstage coupling in single-ended tube amplifier circuits
Provides high inductance of 106 Henrys for stable signal transfer
Supports dual 10k Ohm impedance matching for primary and secondary windings
Ensures wide bandwidth coverage with a frequency range of 20Hz to 20kHz

Applications

Single-ended tube amplifier interstage coupling
Tube driver circuit implementation
Audio signal transformation in vintage or hi-fi amplifier designs

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing specifications may evolve. Confirm that the 10k/10k impedance configuration matches the target amplifier design requirements. Ensure the chassis mount form factor fits the available space within the equipment enclosure. Check for RoHS compliance status if required by project regulations.

Selection Notes

Select this component when a 10k Ohm to 10k Ohm impedance ratio is required for tube interstage applications. The 4W power rating and 106H inductance are suitable for standard audio frequencies. Consider the physical dimensions and mounting holes for chassis integration. This model is distinct from other Hammond audio transformers with different impedance ratios.

Part Context

The 126C belongs to Hammond Manufacturing's line of audio transformers, which are widely used in vacuum tube electronics. These components facilitate signal transfer between stages while maintaining impedance matching. The 126C specifically addresses the needs of single-ended amplifier topologies requiring precise audio frequency response.
