Telefunken Black Diamond E88CC / 6922

That's a strange comment. Do you mean that you would buy them simply because they are stamped with the Telefunken logo, even though they are a JJ design?

If you take a tube, any tube, and put Telefunken on it; is it a Telefunken? May I posit that only a Telefunken is a Telefunken and a non-Telefunken is not a Telefunken no matter what name you put on it?
Of course you can take a Telefunken and put any other name on it and it will still be a Telefunken.

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.
