290SX

Overview

The Hammond Manufacturing 290SX is a power transformer designed for tube guitar amplifier applications, specifically serving as a replacement for Fender amplifiers. It features a single primary winding rated for 100V, 120V, and 240VAC inputs at 60Hz. The secondary configuration includes a high-voltage center-tapped output of 500VAC and two lower voltage outputs of 6.3VAC and 5VAC. The unit utilizes chassis mounting with wire leads for termination.

Feature Summary

Designed as a direct replacement for specific Fender guitar amplifier models
Supports multiple primary voltage inputs for international compatibility
Constructed for tube application circuits

Applications

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

Procurement Notes

Verify the exact input voltage requirements of the target amplifier against the transformer's primary ratings (100V/120V/240V). Confirm that the physical dimensions and mounting hole patterns match the existing chassis layout. Ensure the secondary current ratings meet the circuit's demand to prevent overheating or voltage drop during operation.

Selection Notes

Select this model only when replacing a failed transformer in compatible Fender tube amplifiers. Consider the weight and physical size constraints of the amplifier chassis. Verify that the wire lead lengths are sufficient for the internal wiring layout. Check if the specific reissue version of the amplifier requires this exact part number or an updated variant.

Part Context

This component belongs to the Hammond 290 series, which specializes in power transformers for vintage-style tube audio equipment. The series is widely recognized in the musical instrument industry for providing reliable power supply solutions for classic amplifier designs. It represents a standard industrial control transformer adapted for specialized audio applications.

Replacement Considerations

Verify compatibility with specific Fender reissue models such as the Bassman 59 Reissue. Ensure the replacement matches the original transformer's electrical specifications and physical footprint.
