Started looking 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 and those have a long history of low-Z synergy, and it doesn't need a parallel load resistor on its output. This EI-14 caught my eye though, because it looks like its specifically made for headphone amp circuits. Its small enough to fit inside my darkvoice amp, right next to the Solen coupling cap. Does anyone have experience with this EI-14? At this price point, what are its drawbacks? I am guessing badwidth + frequency extension might be one. Wattage capacity might be another.

LOL yeah that was me. I managed to get through the meet with no upgrade-itis... outside of this thread here.
I can't believe I've never posted here before.

I have a bad case of it. Those Schitt stacks in room 1 has me wanting to raid my savings. I must hold on, must resist............... Sorry I can't answer your question, but I bet someone here has an answer. Cheers, Ron
