Secondary (Output) Impedance *

$62.84

Qty:

Design
Mathematically designed to produce exact plate and screen voltages.

Primary (Input)
The input is designed for a 7.6K Ohms impedance source.

Secondary (Output)
The output is designed for a specified speaker impedance.

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 standard bobbin with black finishing tape.

Termination
The terminations are UL1015 20 ga. lead wire.

Mounting
This unit comes with steel end bells for mounting with the use of four screws. The end bells are powder coated Gentian Blue (RAL 5010) to add to your tube display and overall appearance.

nothing else comes close.

There is no other company out there selling a product this good at a price that comes even close. I have repaired, modified, and built so many push-pull amps I have lost count, and in the process tried many different output transformers, new and used. This amp is the best-sounding amp I have built thus far. Initial listening impression leaves me particularly impressed with how well articulated the bass notes are, and thus far I have not put the amp to use on my largest speakers. I fully expect the same results.

Edcor obviously doesn't cut corners. I was surprised at how BIG and heavy they are. The Hammonds I bought (that cost more) a few years back are noticeably smaller. I am by nature impatient and the wait time is why I have not bought Edcor until now. It's more than worth the wait. My advice is be smart, be patient, buy the Edcors. You'll be enjoying the sound for years to come. Another reason I decided to try Edcor: Real world testing with test equipment and listening tests confirmed Edcor's superiority. That convinced me to give them a try. I do believe there will be more Edcor purchases in my future.

Great Transformers (Regardless of Price)

I used the CXPP25-7.6K for a Stancor "Williamson Amp" project. Based on the limited technical data published by Stancor and my measurements (Audio Precision System 1), I have come to the conclusion that these transformers are just as good (I dare say better, but will say equivalent) as the Stancor A-8072. Listening confirms the measurements. If you want a great push-pull tube amp, build a version of the Williamson with this transformer. Don't listen to the naysayers... build it and listen. You won't regret it.

I previously had Hammonds (1650P/6.6k) in the circuit and prefer the Edcors.
