Any opinions on retubeing W/winged c or mullard re

Do a search in the Tube Forum in Audio Asylum - you will find a lot of comments about the Mullard re-issues, the SED's, and some comparisions of the two.

I have now had 2 sets of the Mullards go bad. I find the Winged are much better sounding and last.

I also have had poor luck with the Mullard reissues. One of four went bad and then another one of four- all this with less than 100 hrs. I'm using EI fat bottle and they have not had a failure- knock on wood. They sound pretty good too.
