UTC PC0-25 nickel core transformer 2K:500 to 600:150. In this test the transformers are configured as a 2:1 step down as used in the alternate input for the Behringer DCX2496 located elsewhere on this website.

Frequency response

Impedance into 20kΩ load. Note that this is a 2KΩ to 500Ω transformer so a 20KΩ load is way outside the expected load.
