Schiit Lyr Tube Rollers - Page 67

I'd refer you to the eBay listing, but the seller used a pic of the '78 Rockets, which have a different construction (at least they were honest enough to state that they used a stock photo that may not match the actual item).  Mine are clearly 1974s.  Irresistible at that price.

I don't want to judge them yet, as I think they really need to burn in.  I did listen right after I rolled them and heard a lot of room for improvement.  Eight or nine hours later I thought they sounded better.  After a couple more hours today, with different tunes, better still.  I like to give whatever tubes at least 100 hours before some seriously critical listening.  Still, the first pair is very promising, esp. with the HD 650s.
Sounds like you have the regular '74. Voskhods with gray shields. The tab you describe in the middle of the top mica is usually referred to as the 'grid'. The shield is the plate that runs between the dual triode plates. This is the same covention used on the Seimens Cca. On the Russian 6n23p on one side this shield runs as a continous plate up to hold the inverted saucer getter called the 'getter post'. All the Russian 6n23ps have the inverted saucer getter.

These are very good tubes, I believe I rated them 6th on my ranking of the '70s Voskhods. And it sounds like you got a bargain, especially if they were well matched. The ones I'm looking for have a single wire the runs up from the shield to hold the getter, as the 'getter post'. These are exceptional beating every tube I have compared them against. Including the '75 Voskhods with gray shield and plate getter post. Including those wonderful USN CEP 7308s I just sold. Only trouble they are so rare. I '73, '74, '75 versions of these wire getter versions, which all sound good. But after weeks of comparing again each other and the USNs, the ones that had the magic where the '74s with silver shields. They added this level of depth and timing to the already excellent detail and musicality of the the top Russians.

My hunt continues. It's so hard, as you mentioned, the pictures don't match what these Russian ebay sellers send you. Good luck!

The E288CC have a insane soundstage that should work wonders with classical. For me the E88CC are my favourite between the two because I just love love the bass from them and they have great soundstage as well (I have the one with double o stage getter). 

 

That's why I'm selling the E288CC while I'm probably keeping the E88CC (still on the fence though because I really really love the Telefunken ECC88 and want a taste of the E188CC). For me they are both very alike. E288CC just have a wider soundstage with less bass. The E88CC still have great soundstage with tighter bass. That's really a matter of preference and musical taste. 

How would you compare the bass of the Siemens E88CC against Bugle Boy, Orange Globes, or the Mullard CV2943?

I already sold the Bugle Boys and haven't listened to the Orange Globes in quite a while (don't know the Mullard, sorry). But the bass is just tight and right. There isn't more of it, it just stands out more. Really hard to explain. If you listen to them, you will know :tongue:

 

There are more than one Siemens E88CC out there obviously. Mine are the double o stage getter with chrome shield.

Thanks for setting me straight re: tube construction.  Yeah, "grid" was the term eluding me.  I like to know what I'm talking about, and sometimes I even think I do! ;)

 

I should say Good Luck! to you.  I'm done buying Russian tubes.  Depending on the Siemens I just got, maybe I'm done for a while.  If not, there may be some Telefunkens in my future :D  My main goal now is a simple one: enjoy some freakin' music!

I was never a big 6922 Tele fan, but love those diamond bottom 12au7, 12ax7 - especially those smooth plates. I run a pr in my moded Jolida 9 phono pre. These Russians have really added some magic to my systems, especially my Maggie 1.6qr/class A amp main, but also in my office Ref 3a Dulcet/class A system. They sound great on the Lyr/HD800/Moon Black Dragon V2 as well. I'm just try to find as many of these wire getter versions as possible while they're still around.

Do the sound signatures of the same make & model tubes, differ that much? 

I've seen people who are very particular, even down to the batch they were created. 

Are GM values a good indication that two of the same tubes match or at least performing the same electrically?

Well you have the Siemens E88CC old D getter from the fifties that are most sought after. Haven't listened to others so can't compare. Just want to clarify in case different getters make different sounds (I'm guessing it will). 

 

Not sure about your last question. Maybe someone else can chime in.

If anyone is looking for that lush, warm Mullard sound, check my posting in the For Sale forum. NOS 1967 Mullard 4109 matched pair. Probably the best Mullard E188CC/7308/6922 tube type made. Incredible with Lyr. Selling my backup pair. PM me.

After listening to the Siemens E288CC today I'm probably keeping these as well, lol. Fell in love with them AGAIN! I have 4 pairs that I really really like now. :D

If you like big soundstage you should!

Do the E288CC types run the hottest compared to 6DJ8s and 6922s?

I'm feeling them right now and they are pretty hot. I have the Tubemonger tubesockets so the Lyr doesn't get too hot. But yeah, I guess so.

To me and the LIMITED tubes I have, yes.  The first pair of Telefunken ECC88 date code eq I think are my favorite tube for the Lyr.  I loved them so much, I bought another set from the same seller.  These were date code eg and they are almost as great as the eq batch, but it's just missing a hint of the dynamics that the first pair have.  Now this could be the difference in the number of hours that the tubes have, but as far as construction and getter type, they are identical to the eye.  

 

I also tried two pairs of Amperex White Label 6922.  One pair date code is 66-37, the other is 66-17.  Both made in the USA, but the 66-17 pair are better than the 66-37.  I find the 66-37 pair lacking in some of the punch that the 66-17 pair has.  The 66-37 pair resemble my Amperex Orange Globes that were made in Great Britain.  The 66-17 pair is probably my second favorite tube and could be on par with my first favorite pair, but it really sounds different than the Telefunkens and not in bad way.

Great now I almost want to buy a second pair of Telefunken ECC88 to try it out :tongue:
