Power Transformers datasheet and documents for 290TRA

290TRA

Power Transformers Overview

The Hammond Manufacturing 290TRA is a laminated chassis-mount power transformer designed for tube guitar amplifier applications. It features a single primary winding rated for 120VAC and 240VAC input at 50/60 Hz. The secondary configuration provides three outputs: a high-voltage center-tapped winding of 320V, a 60V filament winding, and a 6.3VCT heater winding. The unit delivers a maximum current of 252VA with specific ratings of 275mA on the HV section, 1.8A on the 60V section, and 3.0A on the 6.3V section. It utilizes wire lead termination and measures approximately 103.2mm in length.

Power Transformers Feature Summary

Provides multiple secondary voltages including high voltage and dual filament supplies
Features a robust laminated core construction for stable operation

Power Transformers Applications

Fender Bassman 59 Reissue amplifiers
Fender Twin Reverb amplifiers
Fender Deluxe Reverb amplifiers

Power Transformers Procurement Notes

Verify that the replacement transformer matches the original equipment manufacturer's specifications regarding physical dimensions, mounting hole patterns, and terminal orientation. Confirm that the secondary voltage ratings and current capacities align precisely with the amplifier's circuit requirements to ensure safe operation and prevent component damage during installation.

Power Transformers Selection Notes

Select this model when replacing a failed transformer in vintage or reissue tube amplifiers requiring a 320VCT high voltage output. Ensure the new unit supports the necessary filament currents for both 6.3V and 60V tubes. Check for compatibility with existing chassis space and verify that the wire lead lengths are sufficient for the internal wiring layout of the target amplifier design.

Power Transformers Part Context

This component belongs to the Hammond 290 series, which consists of power transformers engineered for musical instrument amplification. These units are characterized by their chassis-mount style and wire-lead terminations, providing reliable power conversion for vacuum tube circuits. The series includes various models tailored to different amplifier power levels and voltage requirements.
