Overview
The Hammond Manufacturing 1650M is a push-pull audio output transformer designed for tube amplifier applications. It features a primary impedance of 1,400 Ohms Center Tap and 800 Ohms Center Tap. The secondary winding provides multiple taps at 4, 8, and 16 Ohms to accommodate various speaker configurations. Rated for 60 Watts of power handling, this component operates within a frequency range of 10 Hz to 280 kHz. It utilizes wire lead termination for circuit integration.
Feature Summary
- Push-pull configuration optimized for high-fidelity audio output stages
- Multiple secondary impedance options for flexible load matching
- Designed for chassis mounting in professional audio equipment
Applications
- Tube-based guitar amplifiers
- Hi-Fi audio output stages
- Professional sound reinforcement systems
Procurement Notes
Verify the specific part number against manufacturer documentation to ensure compatibility with existing circuit designs. Confirm that the primary and secondary impedance values align with the intended vacuum tube specifications. Check for any updated series revisions or redesigns that may affect pinout or physical dimensions before finalizing procurement orders.
Selection Notes
Select this model when a 60W push-pull output transformer is required. Ensure the system design supports the specified 1,400CT/800CT primary impedance. Verify that the available secondary taps (4, 8, 16 Ohms) match the loudspeaker array requirements. Consider the physical mounting constraints and wire lead termination style during the mechanical design phase.
Part Context
This component belongs to the 1608-1650 Series of audio transformers from Hammond Manufacturing. The series includes variants such as the 1650FA and 1650HA, which share similar architectural goals but differ in specific electrical parameters and secondary winding configurations. This series is established for use in high-power tube audio applications.
