Anyone familiar with the Ultron ECC88 tube?

Maybe you should listen first and comment second. Isn't that
the type of response the OP was soliciting when he asked
"or more importantly heard this tube?" Then you
wouldn't have to worry about whether he know tubes (at all),
which he does.

" my dealer just recommended them for my phono. He said they were somewhere between telefunkens and mullards."

That means they should sound like Amperex.

I've got some 60's Bugle Boys and the Ultrons are not nearly as "sweet". Amperex is normally my tube of choice in the ECC83's. I just installed them a week or so ago, so I'm still getting a feel for the tube and I'm sure they need to break-in more as well. I guess I should clarify that I'm talking about the ECC83's not the 88's questioned in the original post. They do have some of the sparkle of the telefunkens. The bass is tighter than the Amperex, but not as warm as Mullards. They're in my phono so the break in process will take longer than normal. I'll report back after another week or so.

Samhar how do you like the Rosewood compared to the Black? Is it worth the extra $$$?
