They look like they are from Feb, 1970. I am not in the market but I do wish people would include test results (not that I would trust them) so buyers can see how well the triodes match.
 

 


I'm tempted. So tempted - and this brings up a basic tube question I have, if someone could indulge me or point me in the right direction:

In cases like this where the seller isn't claiming matched pairs - I reckon any goofball such as myself could get a tube tester and match them at home? Is it just a question of testing them, and if two tubes are within a close range of values, they are deemed to be matched?

Yes, you could buy a tester and test them yourself. I want triodes to be within 5% in a single tube and I would like to see 5% tube to tube match as well. But, up to a 10% difference in both seems to sound fine too.
 
You could buy these tubes and none of them may match.
 
I think you would be better off buying Siemens CCa tubes from these eBay sellers:
 
audiotubes_de
tubesammler
euroklang
 
The first two are the same person. I have purchased from all three and have received great sounding tubes every time.

Cool, thanks. :thu:

I doubt I will get that deep into the tube business, but who knows? It's good to know it's an option.

Well, once I found the tubes I liked, I figured I should buy enough to last 10 or so years. Why? Because I know tube prices aren't coming down and NOS availability isn't going up. If I don't use them, they are an investment for the reasons listed above!

For the asking price I would not expect testing numbers, $200 would probably be accepted, price is priced at the "cheap enough to take a chance on these" level. I heard A3 E88CC and I much prefer the greys myself.

Yes, I only buy gray shields. They have a more realistic sound to them. The gray shield CCa tubes present the music almost uncolored but with depth, clarity, detail, and musicality l that I have not heard with any other tube with the possible exception of the 75 Reflektors HG tubes which are quite close..

Yeah, what they said. If you're going to spend real money on Siemens tubes it doesn't make sense to me to buy anything other than the grey shields.

I personally think its more important to have a single tube match itself and the other tube can be a little off as long as that one is close to matching itself as well. Think of each tube as 2 in 1. It's a dual triode so there will be 2 results for 1 tube.

And yeah, you could buy a tube tester if you'd like. I just go down to my local audio shop and they will test them for free if they aren't busy and I'll just buy a can of deoxit or whatnot. A decent tube tester can ve pricey bu there's a good deal waiting out there for everything, right?

On the Lyr 2, each tube feeds a channel, so I think you want the tubes to match.....

I just want to announce that I bucked up and bought a brand new pair of 75' Reflektor "Holy Grail' SWGP silver shields. I paid more than I wanted to but still a lot less than, say, gray shield 60's CCa's from Eurolaking.. so if it makes an end-game impression on me it's money well spent, right? I guess in a sense were always gambling on whatever tubes we buy...with Ebay Buyer Protection, of course. Hehe

Was it from Svetlana? He does not test for noise, got noisy 74`s from him, they were noisy in my dac but worked ok in the Lyr 2.

I agree, but if your tubes aren't balanced enough I wouldn't even bother using them.

If you want '75 Reflektor "Holy Grail' SWGP silver shields, I would buy them from "kolkoo" here. He tests them and shares the results! I bought three matched pairs from him.
