Anyone heard Svetlana KT-88s?

They are a wonderful, well made, bullet proof tube. Care should be taken as with any power tube to make sure they are burned in prior to matching IF your amp neeeds matched tubes. They ahve a midrange that is a little "prettier" than the 6550C. They look great...nice bottle.

To Trelja - To say a KT88 or 6550 is good or bad, either from the standpoint of sonics or durability, is too simple and just not true. There are good and better of each. And what is good changes. Take the Tesla whgich was supposed to be good, then wasn't, then fixed, then wasn't. You get the picture. The KT88 SHOULD spec out slightly better than a 6550, but that does not mean much. It's like a 8 cylinder engine should be larger in displacement and faster than a 6 cylinder. To simple an answer. Does not work.
