The primary and secondary transformer impedance.

$14.64

Design
Mathematically designed to match line level signals.

Primary (Input)
Designed for a balanced or unbalanced line level signal.

Secondary (Output)
Designed for a balanced or unbalanced line level signal.

Magnet Wire
All units are wound with the finest virgin copper magnet wire. All windings use heavy insulated wire to provide excellent manufacturing yield, lower customer cost and superior life.

The Core
EDCOR uses the finest M6 line grain oriented steel cores. Each unit is hand stacked to assure at least 92% stack.

The Bobbin
EDCOR's royal blue bobbin with black finishing tape.

Termination
The terminations are 0.187" (3/16") quick disconnects.

Mounting
This unit comes with zinc plated channel/frame for mounting with the use of two screws.

An awesome DAC
I tweaked a cheap chinese DAC using these transformers as coupling devices for the output, which is taken directly from the DAC chip.
The sound is amazing, open and liquid.
One of my best DIY, thank you!

EDCOR is a DIY treasure.
Superior quality, handmade in the USA!  I have used this transformer for my build
of the PRR176 vari-mu compressor project.  I used NOS tubes and philips polypropylene throughout the audio stage. I am thrilled with the sound.  I build high end pro audio with the biggest names in vintage and collector transformers and am proud to say that Edcor is an exceptional value, not even considering the competitive pricing.  I have compared to some of the most sought after audio transformers of the same paramaters and I am particularly fond of the midrange character of the audio line.  The power transformers are rock solid and look cool as well, with the blue finish!  Customer service is top notch…EDCOR is a DIY treasure.
