290WX

Overview

The Hammond Manufacturing 290WX is an audio transformer designed for tube guitar amplifier applications, specifically engineered as a replacement for the Fender 63 Reverb. It operates at 120V primary voltage and 60 Hz frequency. The secondary output provides 237V at a current rating of 50mA. This component utilizes chassis mounting and features wire lead termination for integration into existing circuitry.

Feature Summary

Designed for tube guitar amplifier power supply circuits
Engineered to replace original equipment in specific vintage-style amplifiers
Utilizes chassis mount installation with wire leads

Applications

Fender 63 Reverb amplifier restoration
Tube guitar amplifier power supply replacement
Vintage audio equipment repair

Procurement Notes

Verify compatibility with the target amplifier model before purchase. Confirm that the secondary voltage and current ratings match the original transformer specifications to ensure proper operation. Check datasheet details for terminal configuration and physical dimensions to guarantee fit within the existing chassis enclosure.

Selection Notes

Select this unit when replacing a failed transformer in a Fender 63 Reverb or similar circuit requiring identical electrical characteristics. Ensure the new unit supports the required 120V input and 60Hz operation. Consider physical mounting constraints and wire lead length during selection to facilitate installation without modification.

Part Context

This component belongs to the Hammond 290 series of audio transformers, which are widely used in high-fidelity and musical instrument amplifier designs. The series focuses on providing reliable power conversion for vacuum tube circuits, maintaining signal integrity while delivering necessary plate voltages.
