Warm sounding 6922 Type Tubes

What’s a "CCA"?

this is an old stock euro grading of top tier 6dj8/ecc88 type tubes, usually seen in french dutch and german made tubes

these are very rare these days and command very high prices due mostly to their rarity (they sound very nice but not materially better than ’plain jane’ tubes from the period, so long as the latter are well matched and tested)

but if you want a pair of tubes that cost as much as your linestage, then these are the ones to get 🤣

Thanks @jjss49. I assume Telefunken was one company that made them?

Yes @bdp24 -  Siemens and Telefunken made them for the German communications industry. 

CCa tubes are not a sure thing though.  Later vintage Siemens are known to be bright sounding and I don't think the Telefunkens are as highly regarded as the Siemens.  So as with all things tube related, do your homework.

For 15 years, I preferred the large D and/or the large O getter Amperex bugle boys or equivalent.  They tended to have a full bottom end, very sweet mids and slightly recessed highs.  Lovely, just lovely.  

I have avoided the search for Vintage Valves of this type for some time.

There are prices being seen almost appreciated 100% since I was last searching.

My purchasing method, where an agreement with the Vendor is in place that a Tube will be returned for a refund, If my friend with their Valve Tester proves the Tubes supplied measurements are not quite close, when measured on the friends calibrated tester. This method has assisted myself with getting top draw Valves.

With the present prices such a agreement will be even more important, if I have to enter back into being a buyer.

Caveat Emptor - Caveat Emptor, most valves supplied will produce a sound, but what type of Valve is being supplied.

As made known in a previous thread on the E88CC, a New Matched Pair of Gold Lions, had one Valve measuring quite unusual when tested and it was strongly advised not to use it as the Circuit could be detrimentally damaged.
