CXPP25-7.6K

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.  

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.
