Telefunken Black Diamond E88CC / 6922

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