somebody once mentioned, those shaped siemens were made by tungsram (hungary).

Hi Nunki, thanks for writing.
You could elaborate a bit, because first time I hear this for a Siemens tube that could be dated 1968. Unless the code system changed after the Munich factory closure and confused those after 1979 with those made previously.
Anything is possible.
sorry beto, i can not help and i am astonished too about that tungsram-statement.
what i can say is, that "made in gemany" in case of doubt means nothing. european tube manufacturers printed on their tubes what they wanted. only an etched factory code is finally helpful imo.

ps: i just compared a tungsram E88CC with a siemens. the tungsram looks rather different and i am sure your CCa is a true siemens!!

Thanks Nunki!
Still not mine. I am researching before I buy. My local dealer has 3 of these, which he got from a former phone company warehouse. They are too expensive to buy and try, plus the ever present possibility that they are fakes or post Munich productions.
The use I will be putting them to is in my AN DAC. Some time ago I bought a pair of Mullard E188CC, which sound wonderful in the high and mid frequencies, but do not have good bass frequency extension and articulation in my equipment (I clarify), if I compare them with the stock EH tubes that the DAC came with. These EH's have terrific low frequency extension and punch, but sound horrible in the high and mid/high frequencies, full of grain and annoying after a while of listening.
I am now trying a pair of Amperex, orange globe, Holland made from 1966 that I got at a good price. Too early to be conclusive, because I got them a few hours ago, but they already sound quite a bit better down low and don't bother up top, even have more detail than the Mullard, so I can expect everything to improve even more in about 100 hours.
Regarding the Siemenes, they are a temptation, if I can confirm that they are the ones that have been reviewed by many as one of the best along the frequency range. I don't want to go with the hype, in any case, which is partly what keeps these prices high, along with scarcity. A cheap NOS tube may work better, even. You know, if a guy spend a fortune on these tubes, hardly admit publicly that an $80 a pair tube might sound better.
Regards
have a look at this (scroll down a bit). obviously LORENZ used very similar imprints in the web...http://www.jogis-roehrenbude.de/Roehren-Geschichtliches/ECC88-Familie/Lorenz-E88CC/Lor-E88.htm

OK, interesting! Thanks Nunki.
So, Lorenz after 1958 manufactures its tubes in Stuttgard no longer as Lorenz AG but as Standard Elektrik Lorenz (SEL) and uses a 2-line code system.
But this information may mean that the information from the Tube Museum and Audiotubes.com could be incomplete and perhaps does not cover all production, especially from the late 1960s onwards.
Looking at the pictures of those SEL tubes,there is a difference on the board, if that means anything. On the Siemens the two lines of codes are separated by a space and the SEL has no space.
There is still room for more discussion on this point. There is missing information, perhaps because these are rare and expensive tubes and not so many people have been involved.
