Overview
The HS-23 is a hermetically sealed low-level audio interstage transformer manufactured by Triad Magnetics. It features a primary impedance of 15 kOhms and a secondary impedance of 110 kOhms, providing a turns ratio of 1:2.7. The component operates within a frequency range of 20 Hz to 20 kHz and supports an input level of 15 dBu. Designed for chassis mounting with screw termination, it is engineered for single plate to single grid applications in high-fidelity audio circuits.
Feature Summary
- Hermetically sealed construction ensures environmental protection and long-term reliability
- Optimized for single plate to single grid tube amplifier configurations
- Screw termination style facilitates secure mechanical installation
Applications
- Single plate to single grid audio stages
- High-fidelity tube amplifier interstage coupling
- Low-level audio signal transformation
Procurement Notes
Verify the specific impedance requirements against circuit design specifications before ordering. Confirm that the chassis mount form factor and screw termination style align with the enclosure layout. Ensure the operating frequency range meets the audio bandwidth needs of the application. Check for any updated datasheet revisions that may affect pinout or mechanical dimensions.
Selection Notes
Select this component when a 15 kOhm primary and 110 kOhm secondary impedance are required for tube audio stages. Consider the hermetic seal for environments requiring moisture resistance. Evaluate the physical size constraints for chassis mounting. Compare against other Triad models if different impedance ratios or frequency responses are needed.
Part Context
The HS-23 belongs to Triad Magnetics' line of hermetically sealed low-level audio transformers. These components are designed for precision audio applications where signal integrity and durability are critical. The series typically includes various impedance options tailored for different tube amplifier topologies.
Replacement Considerations
