Started down the mod-path the other week and am scoping output transformer mods to my various OTL amps.
The Hammond 119DA thus far is one I am considering, being that its used in the mapletree MAD Ear amps.
This EI-14 caught my eye though, because it looks like its specifically made for headphone amp circuits. Does anyone have experience with this one? At this price point, what are its drawbacks? I am guessing badwidth might be one.
