Nice! Are your Reflectors the ones with the dual dimpled getter posts? Or single wire? Yes Russian glass is very sweet to the ears...thanks for the feedback.

Dual posts, though I was expecting the dimples to be two round indentations, rather than the vertical "line," but clearly it's a raised portion on the getter posts (and now I know what you mean by "dual"... as in two posts... duh.  Still waking up ;-)

 

My '74 Rockets have the curvy single wire getter post.

Yeah, I call them dimples, but they more like indented lines on the post plate, and the posts are on each side of the invertered saucer getter. I'm curious to hear your comparison of these and the '74s

Late this week they'll have roughly the same number of hours on them as the Rockets, then I'll start rolling.  Then I'll go back to my Siemens CCas and see what's what ;)

:P

Sound is much warmer, when I heard violins it sounded like I was right next to the violinist.
On the other hand we've got more realistic sound, and now that I've plugged my HD700 (after listening for a little bit with my LCD-3) and first thing I noticed was a momentary hiss which disappeared almost instantly, is it something I should be worried about?

Also, I've noticed that gain is less than the stock tubes?

I'm considering that with some burn in of the tubes it is going to be much better just like the stock tubes did... but so far I'm enjoying it, not fatiguing sound smily_headphones1.gif

Now to wait for the Auralic Vega and omg I'm gonna have a real high end setup biggrin.gif
What year are your 6n23p? That Vega is one sweet dac! Did you read the 6moons review? Dedicated DsD and DxD chips? http://www.6moons.com/audioreviews/auralic5/1.html

Also, did you test those tubes? They should have pretty close to the same gain as the GEs, and no noise. A lot of the tubes I'm getting from Russia/Ukrains/Moldova have one weak section - even the ones claimed to be NOS. 6n23p like 6922 tubes have two sections per tube. So both sections need to be tested and matched, then across the pr.

Wow Seimens CCa! Are these the gray shields from the '60s? That's stiff competition! Can't wait to hear your comparisons.

Silver shields I think, from 1969 (There's a silver "post" extending through the shield, on which is stamped the production info: A4 / 9L).  Not 'A' frame.  Got them from a German eBay seller.  I did a lot of research on CCas and found a post on Audio Asylum that ranks the CCas.  That seller was asking $60 more for the later production '70s (thin wire getter post) that rank lower (and described as "schiity" ;-).  So, I feel like I got a good deal.

 

This post has photos and ranking:

Mine are #3.  Gray shields are a lot more expensive, or were when I was looking, but they do show up now and then.

1983 Reflectors | Stock GEs (came with Lyr)

Are these the tubes that simply didn't past testing? (but would still play music in an amp or whatever) Or are they really so dead (ie. burnt out?) that they won't play anything at all?

Here is a really good site, just look under 6922, half way down is a ranking of Seimens CCas. Years ago I had quite a collection, the early '60s gray shields are quite abit better then the later silver shields. Never could find the '50 U getters - the rarest of the rare.

My boxes are full ;)

 

Maybe next year I'll go hunting again, but it'll have to be a really good deal to get the Siemens gray shields or '60s Telefunken E88CCs.  I need to save my quarters and dimes for the HE-560s :D

Both, a tube will fail my testing if: 1) it's dead or shorted, 2) either section does not come to at least 90% of NOS or there is a wide spread in section outputs, 3) either section fails the gas emissions test, 4) has noise issues in my Lyr. Now you might say well a tube testing at 80% of NOS is still playable, and that is true, but in my experience they begin to decline from here fairly quickly. So not really worth messing with. Same for big spreads in section testing, say one at 95 and the other at 86. In my experience this leads to a muddied sound, loss of detail, narrow soundstage, poor imaging. Same goes for bad matching of output in a pr. Also mixed pairs with different yrs, shield colors, constructions. These rob from the detail, soundstage and imaging, and looses some of flow. These are some of the best traits of the best 6n23p. You haven't heard what these are capabile of until you've heard a well matched pr.
