Waterfall:
You may be right about keeping quite about Japanese tubes. There is still a good amount of "snob" bias out there from many I'm sure have not even given them a try.
The tube you posted is not the same tube as the Hitachi's I have. My pair is already in my headphone amp, or I would take a close-up. So I copied two photos from the web that shows the construction and are posted above.
I spent a good amount of time checking EVERY detail of the internals of the Tel-Rad labeled ones I purchased. Also, the print on the base (6SN7-GTB) has a distinctive print style of letters and numbers, and the Tel-Rad and Hitachi are a match there also.
