Siemens Halske versus Siemens Rohre

Nice link Tvad. I have 4 pairs of the early gray riser Siemens( some call them gray plates) and all have the codes on the glass but one.
But they are ECC88 not CCa, although CCa are said to be the pick of the litter from ECC88.

Semens & Halske E88CC

Characteristics:

- double stage getter

- AØX ≠XX code on getter support

Comment:

Quite rare.

That is the info from the website. I think a bit of an oversight as most I have seen that have the codes on the getter support are the silver riser.

I have 8 tubes with the AØX ≠XX code. 7 being gray riser with code on glass and 1 gray riser with code on getter support.

Go figure!

I also found the ECC88 gray riser to be better then the later CCa silver riser. YMMV

This is my favourite tube from the 6JD8, 6922, 7308 family.

Benie, I have owned Siemens E88CC (not ECC88) grey riser tubes, and they are EXCELLENT (and inexpensive...relatively speaking). In fact, they are my second favorite Siemens tubes next to CCa. Yes, you can hear the difference between CCa and grey riser Siemens E88CC, but for many people (myself included) the higher price of the CCa is not worth the expense for the small tonality gain over the E88CC grey riser tubes.

FWIW, to my knowledge, all Siemens CCa are E88CC/6922. Any E188CC or 7308 being sold as CCa are not CCa at all.

If you have your mind set to go for some rare Siemens CCa tubes on Ebay, bid your max because there will be last second snipers lurking nearby.

Are you one of the snipers this week:-) Hate to bid against a friend!

If you happen to choose Ebay to shop for tubes, there are alot of fakes out there so make sure you do your homework. There is a dealer name bugleman that sells alot of counterfeits, look up bugleman on the audioasylum, there is quite a bit of write up on him. Yes, I did get burn by him years ago buying a pair of CCa's. But, it was my fault for not researching before I bought.

Good luck!
