107X

Overview

The Hammond Manufacturing 107X is a potted audio output transformer designed for push-pull tube output circuits. It serves as a general-purpose component for audio signal coupling and impedance matching in vacuum tube amplifier applications. The unit features a robust potted construction to secure internal windings against mechanical vibration, ensuring consistent electrical performance in high-vibration environments typical of musical instrument amplifiers.

Feature Summary

• Potted construction provides mechanical stability and protects internal windings from vibration-induced microphonics.
• Engineered specifically for push-pull tube output circuit configurations.
• Designed for general-purpose audio signal coupling and impedance transformation.

Applications

• Push-pull tube audio amplifier output stages
• Vacuum tube guitar amplifier construction
• Audio equipment repair and replacement

Procurement Notes

Verify the specific primary and secondary impedance values required for your circuit design before ordering, as these are critical for proper tube load matching. Confirm that the physical mounting dimensions and terminal configuration align with your chassis layout. Ensure the component meets the thermal requirements of your enclosure. Cross-reference the datasheet specifications with your amplifier's tube type to guarantee compatibility.

Selection Notes

Select this transformer based on the required impedance ratio for your specific tube pair (e.g., EL34, 6L6). Consider the power handling capacity relative to your amplifier's output stage. Evaluate the physical size constraints within the amplifier chassis. Verify that the potted design suits the environmental conditions of the installation.

Part Context

This component belongs to Hammond Manufacturing's line of audio transformers, which are widely used in vintage-style and modern tube amplifier designs. The brand is recognized for producing reliable magnetic components for audio applications. This specific model is part of their general-purpose audio transformer series, catering to both manufacturing and repair markets.

Replacement Considerations

When replacing an existing unit, ensure the new transformer matches the original impedance ratio and power rating. Verify that the pinout or terminal arrangement is compatible with the existing wiring harness. Check if the physical footprint allows for direct substitution without modifying the chassis or mounting brackets.
