These are surprisingly good sounding transformers i would highly recommend them, i have been testing all kinds of transformers on the same motors to evaluate them and i really like these, real rich and low hum noise floor. and what a great price…

works exactly as intended in my first ribbon mic 🙂

I have T-bone Rb100 mic. I replaced original transformer in this mic with T25. And the result is fantastic. Very low noise floor. This is great improvement to this low price ribbon mic. Original RB100 mic had very poor grounding compared to T25 transformer. Really rich and addictively mellow ribbon sound! Highly recommended for DIY projects and transforemes upgrades.
