260E

Power Transformers Overview

The Hammond Manufacturing 260E is a power transformer belonging to the 'Classic' series, designed for plate and filament applications. It features a steel laminated core construction with a black oxide finish on the casing. The unit utilizes a phenolic base for mounting stability and includes a protective metal shield over the windings. This component serves as a general-purpose power supply element in electronic circuits requiring isolated voltage transformation.

Power Transformers Feature Summary

• Provides dedicated secondary outputs for plate and filament voltages
• Constructed with a steel laminated core for efficient magnetic coupling
• Features a phenolic base for secure mechanical mounting
• Includes a protective metal shield covering the internal windings

Power Transformers Applications

• Vacuum tube amplifier power supplies
• Audio equipment transformer stages
• General purpose plate and filament voltage conversion

Power Transformers Procurement Notes

Verify the specific pinout configuration and voltage ratings against the target circuit design before integration. Confirm that the physical dimensions of the phenolic base and mounting holes align with the chassis layout. Ensure the operating frequency matches the system requirements. Review the datasheet for thermal dissipation characteristics to determine adequate cooling provisions within the enclosure.

Power Transformers Selection Notes

Select this model when a dedicated classic-style transformer for tube-based electronics is required. Consider the physical footprint constraints imposed by the rectangular casing and base. Evaluate the available secondary voltage taps to ensure they meet the load requirements without excessive regulation loss. Compare alternative series options if different mounting styles or shielding levels are necessary for the specific application environment.

Power Transformers Part Context

This component is part of Hammond Manufacturing's 'Classic' series of power transformers. The series is characterized by traditional construction methods using steel cores and phenolic bases. These units are commonly specified in retro-audio and vintage-style electronic designs where form factor and aesthetic consistency with older equipment are prioritized alongside functional performance.

Power Transformers Replacement Considerations

Direct substitutes may include other Hammond models from the same series with matching voltage ratios and current capacities. Verify compatibility with existing mounting hardware due to potential variations in base hole patterns. Cross-reference secondary winding configurations to ensure electrical equivalence in plate and filament delivery.
