Default Single Ended Ultra linear, ne1 built one?

This seems to be a rather rare form of amp and I am wondering if anyone has built one on this site? Is so could you tell me a little about it's design and it's over all sound compared to a SET?

Yep, some people have built them. But I haven't.

One of those pages was referred to on a forum by the builder... don't remember if it was diyAudio though.

I am curious to hear an amp like this. I love the sound of my SET but I wonder if it could be crought to another level. I think I am going to try to make the first amp a build a SEU amp.

I'd be interested as well for the next project. Didn't Harvey Rosenberg have a 5881 version?

Not Rosenberg, Morrison's Fi Primer! That bugged me for a week. Here's a link to the 6L6 UL SE circuit:

I built one from this schematic and it sounds very good.
