A buddy of mine has used them. He compared performance to the Hammond 125 series.

perhaps the bandwidth should be measured in MB/sec instead of Hz...

So judging by the specs of the Hammond 125 series, it not really worth considering for a serious project.
I never noticed the picture was wrong, I just thought it was a really unusual design for a transformer.

I'm afraid that as far as output transformers are concerned, bigger really is better.

That might be a little unkind. Remember that feedback compensation networks are invariable specific to the output transformer and its usage.

Gentlemen,

Just because something is small with less than Hi-Fi specifications, doesn't mean it's poor. If it sounds good, Great!

There's a lot of bad sounding things on the market with great specs and a lot of great sounding things that are lousy on paper.

One of the finest truism's I have read came from member BHD, "There are lies, damn lies and specs."

If *you* like the sound, go for it! But there's only one way to find out

Cheers!
