Telefunken Black Diamond E88CC / 6922

Rja,
You may have overstated a little...but that was my point.

Roxy, I know, I was just bored.

Roxy, the thread states "anybody tried these new tubes ?" I will buy some and try them.

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.
