1650W

Overview

The Hammond Manufacturing 1650W is a high-power push-pull audio output transformer designed for tube amplifier applications. It features a primary impedance of 1,900 CT and supports a maximum DC current of 806 mA. The unit delivers a power rating of 280 W with secondary taps available at 4, 8, and 16 Ohms. Operating within a frequency range of 30 Hz to 30 kHz, the device utilizes wire lead termination and includes shielding to minimize interference. Its physical dimensions are 5.25 inches in height, with a bulk packaging format suitable for chassis mounting in high-fidelity audio systems.

Feature Summary

Push-pull configuration optimized for high-power tube output stages
Integrated electromagnetic shielding for signal integrity
Multiple secondary impedance options for flexible speaker matching
High current handling capability for demanding audio loads

Applications

High-fidelity tube amplifier construction
Professional audio equipment output stages
Custom guitar amplifier modifications
Vintage audio restoration projects

Procurement Notes

Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct impedance and power ratings. Confirm that the 280W rating aligns with your amplifier's thermal design. Check datasheet specifications for insulation voltage and DC resistance values prior to integration. Ensure compatibility with existing chassis mounting requirements and wire lead lengths.

Selection Notes

Select this component when designing amplifiers requiring substantial power output exceeding standard consumer-grade transformers. The 1,900 CT primary impedance suits specific tube types such as EL34 or KT88 in push-pull configurations. Consider the physical height of 5.25 inches for enclosure space planning. Evaluate the 806 mA DC current limit against your circuit's quiescent current requirements to prevent saturation.

Part Context

This model belongs to the Hammond Manufacturing 1608A-1650 series, which focuses on classic audio transformers for tube applications. The series provides proven magnetics for hi-fi audio and guitar amplifiers. The 1650W represents the high-power variant within this portfolio, distinguished by its 280W rating and specialized primary winding for low-impedance tube pairs.
