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
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.
