Description

The LL1663 transformer is offered in three factory-set configurations, each with a different air-gap optimized for its intended operating mode:

  • Push-pull

  • Single-ended, 50 mA

  • Single-ended, 100 mA

(The air-gap is designed to handle the DC current from the output tube without driving the core into saturation, ensuring adequate headroom for the audio signal.)

You can also choose between two types of C-core materials:

  • Silicon-iron

  • Amorphous-iron (AM)

The transformer’s primary and secondary impedances can be configured by wiring the exposed solder pins in different combinations of the internal winding sections.
