Hello,

I got 2-3 pairs of Siemens CCa in NOS or like new condition. They are all in the 100-130% on tube tester.

Those are 6dj8, E88CC, ECC88, 7308, 6922 equivalent.

I'm asking for 205$US shipped per pair and one pair will go for 190$US shipped.

Let me know if you are interested.

Thanks

Laurent

More information would be appreciated: example: year of manufacture, date codes, original boxes, pics to show lettering and internal construction....etc. will be very helpful.

Also, are they matched ? were they tested for microphonics ? Also, NOS and "like new" are different and I would suggest the seller be more specific.

For tubes at this calibre I would suggest more information is needed to make a purchase decision.

Siemens CCa Tube NOS or Like new (same family as 6dj8, 7308, 6922, etc.)



Here's a little description from the seller I bought it from:

Markings on the getter supports are A6 3B and on the glass 273. Made in Germany. The CCa is a low noise, premium version of the 6DJ8/6922. Transconductance is 13,000-12,500 uM on one tube and 11,500-12,000 on the other. Normal transconductance is 12,000 uM for new tubes.

The others:



Markings on the getter supports are A6 4B and on the glass 374. Made in Germany. The CCa is a low noise, premium version of the 6DJ8/6922. Transconductance is 12,000-12,000 uM on one tube and 13,000-13,000 on the other. Normal transconductance is 12,000 uM for new tubes.

Those are the cream of the cream in the 6dj8/7308/6922/E88CC/ECC88 family. Excellent and rare tubes. Excellent price.

darn, I'm shopping for a 6922 pair right now, but these are just too far above my budget. Good luck with the sale! Great tubes for a really good price.

You should not underestimate the importance of a good pairs of tubes in a system. Those are the best for a 6922/7308/6dj8 setup.
