RE: Help identifying E83CC

So, in furtherance of full disclosure, I do not have any Siemens 12AX7 examples around to compare. I do, however, have a number of Siemens 6922 and 7308 tubes in my stash. Comparing construction clues from the pics and your description to the Siemens examples I have, I'm reasonably confident in saying those are the real deal Siemens tubes.
