RE: CCa Siemens Identification (with actual photos)

That's an odd tube per my understanding of Siemens tubes of that era. I believe most if not all Siemens tubes made in Halske during the period that had silver tags had 3 lines of codes on the tags and the tops of the tubes would have 4 seams. I didn't notice any seams on your tube.

Your tube is missing the middle of the 3 lines of codes and note that the code particular to a Halske manufacture would be on that line. And there is no code for a factory within the 2 code lines on the tube's tag.

The 8J code, if it was a Halske Siemens, would indicate October 1968. 8 = 1968 and J = October. An "A" would indicate January.

Perhaps this is an East Euro made tube.
