Hi None of these transformers are designed for audio use. The same is true of the various inductors and capacitors mounted up on power poles to try to phase correct the distribution process. Pretty much all of them are “out in the wild” and thus exposed to fairly large temperature swings.
All of that suggests that the typical power distribution line is pretty narrow band / low pass. Indeed back in the day, that’s what we found when measuring this and that. I’d vote for sticking with the transformer. Bob > On Jan 21, 2022, at 10:16 PM, Keelan Lightfoot <keelanlightf...@gmail.com> > wrote: > > I was pondering this recently.
