Overview
The Hammond Manufacturing 1650K is a push-pull audio output transformer designed for tube application power circuits. It features a primary impedance of 3,400 center-tapped ohms and supports secondary impedances of 4, 8, and 16 ohms. The unit has a power rating of 50 watts with a maximum DC current capacity of 318 mA. Operating within a frequency range of 30 Hz to 30 kHz, it utilizes wire lead termination and includes shielding. The physical dimensions are 4.000 inches in length by 3.130 inches in width.
Feature Summary
- Push-pull configuration optimized for high-fidelity audio and ultralinear tube output stages
- Multi-tap secondary winding providing selectable impedance matching for various speaker loads
- Shielded construction to minimize electromagnetic interference and hum induction
Applications
- High-fidelity vacuum tube amplifier output stages
- Ultralinear tube amplifier circuit integration
- Professional audio equipment signal transformation
Procurement Notes
Verify the specific primary impedance requirement against the design schematic, as this model specifies a 3,400 CT primary. Confirm that the 50-watt power rating aligns with the thermal management capabilities of the target enclosure. Ensure the wire lead termination style matches the existing wiring harness or PCB layout constraints before finalizing the order.
Selection Notes
Select this component when a 50-watt push-pull output stage requires a 3,400 CT primary impedance. Compare against the 1650E (15W) and 1650HA (40W) variants if lower power ratings are sufficient for the application. Consider the physical footprint of 4.000 x 3.130 inches for chassis mounting compatibility.
Part Context
This part belongs to the Hammond 1600 series of audio transformers, which are engineered specifically for tube-based audio amplification. These components serve as critical interface elements between vacuum tube plates and speaker loads, ensuring efficient power transfer and impedance matching across the audible frequency spectrum.
