Anyone used a edcor cxpp100-ms-5k OT

Hi all,

Just trying to find some opinions on the edcor cxpp output transformers. Have you had any luck with them or are they crap?

Thanks,
Nick

I have used the version with only the 8-ohm secondary. It sounds pretty good, but i have no measurements to back that up. They look really nice, too.

Any transformer is a complex beast with own character. I use Edcor transformers in my amps. Even if you order transformers for your requirements anyway you have to tweak the amp because they are most expensive parts.
Edcor offers very good transformers for a reasonable price. You can find cheaper source in China, but don't expect such repeatability of parameters. You may get good Chinese samples, but when order a party you may get something different.

I have these running in some 829B push-pull monoblocks. The price is reasonable, the frequency response is good, and the performance seems more than reasonable for a product at this price. I wouldn't hesitate to use them over Hammond.

I own a pair of those Edcors:
Good iron, good leads, good windings, no probs...
Excellent packing protection for rough shipping.

On the downside:
Thin endbell tabs (by comparison to Hammond).
Such a weighty beast deserves stronger mounts.

Took about 3 weeks to get here, and they never
sent the confirmation emails they promised twice.
But hey, I did eventually get the iron. It may have
been delayed by a custom I had them make for
the same order? I don't know the real reason.

Edcor logo printed on a clear sticker, peels right off...
If not extra careful, easily gets bubbles and/or dirt
trapped under the edges...

Minor complaints seem trivial by comparison to my
satisfaction with function and appearance of the
CXPP product. Worth every penny and then some.
Definitely would buy Edcor again and again.
