I have a old set of Toshiba headphones that are transfomer driven, in separate box.
they are 20 to 20k response. The panel or wire in one (left or right headphone) is dead. I am wondering if the transformers might be good for MC cartridge loading. Any guesses? I can do the test work myself.. but thought I'd ask you guys and maybe create a discussion on this odd subject. |

doubtful. the headphone transformers have high turns ratio
to drive high impedance (actually small capacitance) 'phones.
MC needs very low Z to not-so-low Z and much shielding.
The two sets of requirements are almost diametrically opposed |

| I failed to mention: The headphones are speaker level input only. they need to be driven by a power amp. Like the stax SR-44's I have. Same thing. So they are definitely low z on the one end.. Sorta. Maybe. Perhaps you took this into account in your reply. Thanks for your effort! |

Even if the impedances match your into an area I seldom see discussed.
The transformer will be too large, it would need too much magnetisation current ?
As far as I'm aware the smaller the transformer the better for MC's,
due to I presume due to low magnetisation / hysteresis loss ?

also, the turns ratio needed for the ES headphones will be
far greater than you need for the MC cartridge |
