Well the primary and secondary impedances are drastically different, so, yeah, what are you going to use it for? In tube circuits, the primary impedance has to match the high impedance of the tube, and the secondary has to match the output device usually a speaker.
The TY-141P datasheet(s) appear to NOT show the inductance anywhere. But when measured with a Peak Atlas LCR45, it it seems to have an inductance of about 10H on both the primary & secondary windings. Not really sure the inductance has any bearing in a pedal.And what about the inductance of the TY-141P? I can't find this information.
