Mullard 12au7 cv4003 tubes? any good?

anyone using the mullard 12au7 tubes that are from the late 70's early 80's? Many seem not to like them, but they are easily had at reasonable cost, so I was wondering if there are any more detailed opinions out there. It is for a Unison Unico integrated. Thanks,

Thanks for both answers: I'll give them a shot. And Jacob, any suggestions on trustworthy sources for other stuff would be great.
