290VX

Overview

The Hammond Manufacturing 290VX is a power transformer designed for tube guitar amplifiers, specifically serving as a replacement for Fender models. It features a single primary winding rated at 120 VAC and operates at a frequency of 60 Hz. The secondary configuration includes a high-voltage center-tapped output of 630 VAC alongside two lower voltage taps providing 6.66 VAC and 5.1 VAC. Current ratings are specified at 92 mA for the high-voltage circuit, 4 A for the 6.66 V circuit, and 3 A for the 5.1 V circuit. The unit utilizes chassis mounting with wire lead terminations.

Feature Summary

Designed specifically for tube application in guitar amplifier circuits
Provides multiple secondary voltage outputs to support various amplifier stages
Features a robust chassis mount construction for stable installation

Applications

Replacement power supply for Fender tube guitar amplifiers
Custom tube audio amplifier builds requiring specific voltage taps
Restoration of vintage musical instrument equipment

Procurement Notes

Verify that the replacement transformer matches the physical dimensions and mounting hole patterns of the original unit to ensure proper fit within the amplifier chassis. Confirm that the wire lead lengths are sufficient for the intended routing paths inside the enclosure. Check for compliance with local electrical safety standards before integration into commercial or public-facing audio systems.

Selection Notes

Select this model when a direct replacement for Fender-style tube amplifiers is required. Ensure the primary voltage rating aligns with the local mains supply frequency and voltage. Verify that the secondary current capabilities meet the total load requirements of the amplifier's rectifier and bias circuits without exceeding thermal limits.

Part Context

This component belongs to the Hammond 290 series, which specializes in power transformers for tube-based audio equipment. The series offers various configurations tailored to different amplifier designs, ensuring compatibility with classic tone stacks and power supply architectures used in professional and consumer-grade musical instruments.
