1650KA

Overview

The Hammond Manufacturing 1650KA is a push-pull audio output transformer designed for tube amplifier applications. It features a primary impedance of 3,400 CT and supports a maximum DC current of 318 mA. The secondary winding provides selectable impedances of 4, 8, and 16 Ohms. Rated at 50W power capacity, the unit operates within a frequency range of 30 Hz to 30 kHz. It utilizes terminal connections for installation and includes shielding to minimize interference.

Feature Summary

Push-pull configuration optimized for tube output circuits
Selectable secondary impedance taps for 4, 8, and 16 Ohm loads
Shielded construction to reduce electromagnetic interference
High bass frequency headroom capability

Applications

Tube-based hi-fi audio amplifiers
Guitar amplifier output stages
Push-pull tube circuit designs
Audiophile audio equipment

Procurement Notes

Verify the specific datasheet version for the 1650KA model to confirm terminal pinout and mounting hole dimensions. Ensure compatibility with the target tube pair's plate-to-plate impedance requirements. Check for RoHS compliance status if required by the final assembly specifications.

Selection Notes

Select this component when a 3,400 CT primary impedance matches the tube configuration. The 50W rating must exceed the amplifier's peak power demands. Verify that the physical dimensions accommodate the chassis layout. Consider the weight and size constraints associated with high-capacity audio transformers.

Part Context

This part belongs to the Hammond 1650 series of audio transformers. It shares design characteristics with models like the 1650E and 1650HA but differs in primary impedance and power rating. The series is known for robust construction suitable for high-fidelity audio reproduction.
