The transformer is designed for high end audio applications such as tube amplifier line input with or without phase splitting. The windings are arranged to give a high degree of symmetry if the transformer is used for phase splitting. The dual-coil structure also greatly improves immunity to external magnetic fields from e.g. power supplies and motors. Primary and secondary windings are separated by electrostatic shields.. The transformer is housed in a mu-metal can.Suitable transformer for 1:1 applications with 600 ohm source and at least 10K reflecting impedance output 600/10K.

Good transformers for interconnect. LL1588/LL1592/LL1590 are good transformers for audio signal, which can be used in high-end audio system. I used these transformers for galvanic isolation and filtering like Jeff Rowland. Distortion is extremely low and Lundahl is a serious supplier for such items. Transformers are still limited to low frequencies. These three transformers support about 7Vrms at 20Hz without visible distortion on a sinusoidal signal. For the perfectionist guys, I suggest adding an RC element to have flat bandwidth and good transient response, and maybe a series capacitor as well. The question remains: mu-metal core or cobalt-based core? Mu-metal seems safer...
