Overview

The 1609 is a high-fidelity push-pull tube output transformer designed for premium audio applications. It features a frequency response of 30 Hz to 30 kHz and is compatible with common output tubes such as the 6V6, EL84, and 6BQ5 in triode, pentode, or ultra-linear configurations.

Why Choose This Part

This transformer provides excellent linearity with a maximum 1 dB deviation across its rated frequency range. Its robust chassis-mount design includes insulated flexible leads and plastic coil forms for reliable insulation and ease of integration into point-to-point wired tube chassis.

Applications

Hi-Fi Tube Amplifiers
Ideal for push-pull power stages using EL84 or 6V6 tubes in high-fidelity home audio systems.
Ultra-Linear Pentode Stages
Designed with screen taps to support ultra-linear circuit topologies for reduced distortion.
Instrument Amplification
Suitable for premium guitar or bass tube amplifiers requiring a wide frequency response and specific primary impedances.

Getting Started

When integrating the 1609, ensure proper orientation to minimize electromagnetic interference with power transformers and sensitive preamp stages. Refer to the lead color-coding for primary, secondary, and ultra-linear tap connections as specified in the Hammond technical documentation.
