Siemens CCa Vs. E88CC, what's the phisical diff?

Posted by atjandra888@yahoo.com (A) on September 11, 2005 at 08:15:08

Hi,
Currently I try to upgrade my SFL-2 tubes and have some offer of Siemens tubes. Some of them are labeled as CCa (the CCa word is still there), however some others only have partial label such as "CC" or even no label at all. However, as I notice the word "CC" is not located in the middle of the Siemens logo, I suspected some tubes might be the E88CC instead of CCa. I also have checked according to "Joe's Tubes Lore", all of them had the ridges, all grey between the mica support, and double digit numbers on the bottom of those tubes. Thus, I may say that they are highly unlikely to be fake tubes.
However, I also notice that those CCa, suspiciously E88CC and all-wiped-off-label tubes, to have the same internal structure (or may I say exactly the same). Therefore, are those Siemens E88CCs basically the same tubes as CCa? How could I differentiate them (or how would I know whether the tubes w/out label to be CCa or E88CC)?
Please help...
Thanks so much.

Regards,
Adinata
