Telefunken Black Diamond E88CC / 6922

That's good. I hope that they work well for you.

Slikric,
You should try them, why not? They may be great and you'll never know until you try them. Good luck to you.
The Telefunken labeling moderately bothers me because IMO it's a marketing gimmick which does not necessarily mean the tube is without merit.

Apologies Roxy. I have no idea why I read it that way. :-)

Noromance,
Not a problem. It's easy to misread things.
