290EAZ

Power Transformers Overview

The Hammond Manufacturing 290EAZ is an industrial power transformer designed for tube guitar amplifiers, specifically the Fender 94 Twin Reissue. It features a single primary winding rated at 120 VAC and operates at a frequency of 60 Hz. The secondary configuration provides a center-tapped voltage of 365 VAC with a current rating of 850 mA. This component utilizes wire leads for termination and is intended for chassis mounting applications.

Power Transformers Feature Summary

• Designed for high-voltage plate supply in tube-based audio equipment
• Single primary winding construction for standard line voltage input
• Center-tapped secondary output optimized for rectifier circuits

Power Transformers Applications

• Fender 94 Twin Reissue amplifier restoration
• Tube guitar amplifier power supply replacement
• Industrial control transformer applications requiring specific voltage ratings

Power Transformers Procurement Notes

Verify that the replacement unit matches the original specifications exactly, particularly the 365Vct secondary voltage and 850mA current rating. Confirm the physical dimensions and lead lengths are compatible with the existing chassis layout to ensure proper installation without modification.

Power Transformers Selection Notes

Select this model only when the application requires a 120V primary input and a 365Vct secondary output. Ensure the current capacity meets or exceeds the circuit's maximum draw. Verify compatibility with the target amplifier chassis before procurement.

Power Transformers Part Context

This transformer belongs to the Hammond 290 series, which includes various models tailored for different tube amplifier configurations. The 290EAZ is distinct from other variants like the 290TX due to its specific voltage and current ratings suited for twin-reverb style amplifiers.

Power Transformers Replacement Considerations

Direct substitutes include Hammond 290EAZ equivalents from authorized distributors. Cross-reference with Hammond 290 series documentation to confirm pinout and dimensional compatibility.
