1760H

Overview

The Hammond Manufacturing 1760H is an output transformer designed for guitar amplifiers. It features a primary impedance of 6,600 ohms center-tapped and secondary impedances of 4, 8, and 16 ohms. The unit supports a power rating of 20W. This component belongs to the 1760 series and is intended for use in audio signal transformation within tube amplifier circuits.

Feature Summary

Provides multiple secondary impedance options including 4, 8, and 16 ohms
Features a 6,600 ohm center-tapped primary winding
Designed specifically for tube guitar amplifier applications

Applications

Fender Deluxe Reverb 68 Custom
Fender Deluxe Reverb 65 Reissue
Tube guitar amplifier output stages

Procurement Notes

Verify compatibility with specific amplifier chassis dimensions and wiring configurations before procurement. Confirm that the 20W power rating aligns with the target amplifier's design requirements. Ensure the center-tapped primary matches the existing circuit topology. Check for any regional shipping restrictions due to product weight or size limitations when placing orders.

Selection Notes

Select this transformer when replacing failed units in compatible Fender amplifier models requiring a 6,600 ohm primary. Consider the 20W power handling capacity relative to the amplifier's output stage. Verify that the multi-tap secondary configuration (4/8/16 ohms) matches the speaker cabinet connections required by the specific amplifier variant being serviced or built.

Part Context

This component is part of Hammond Manufacturing's 1760 series of audio and signal transformers. It serves as a specialized replacement or build component for vintage-style tube guitar amplifiers. The product falls under the broader category of audio transformers used in musical instrument electronics.

Replacement Considerations

Direct replacements include other Hammond 1760 series variants if electrical parameters match. Verify pinout and mounting hole alignment against the original factory unit. Ensure the replacement maintains the specified 6,600 ohm primary impedance to preserve amplifier tone characteristics.
