Shielded construction to minimize interference in broadcast environments.
Configured for interstage signal coupling with specific impedance matching options.

Applications

Push-pull tube output circuit replacement
Broadcast audio equipment
Hi-fi amplifier interstage coupling

Procurement Notes

Verify the specific impedance configuration required for your circuit design, as the part supports multiple primary and secondary impedance values. Confirm physical mounting requirements against the specified dimensions. Ensure compatibility with existing tube-based architectures before procurement. Check current availability status through authorized distributors due to potential supply variations.

Selection Notes

Select this component when replacing interstage transformers in vintage or specialized tube amplifiers requiring specific impedance ratios. Consider the shielded design for noise-sensitive broadcast applications. Evaluate the physical size constraints against available chassis space. Verify that the frequency response meets the audio bandwidth requirements of the target system.
