Eh ... warmed up for around 30 minutes and than gave it a listen for 2-3 hours. Does it change significantly ? Feel like noob now 

 
 
Absolutely!  Give them 20 hours, then listen again.
 
I'm not saying that these tubes will definitely turn into gems, but they will most likely change, and may change quite a bit.  
 
Some say that you need to give a tube 100 hours to really finish burning in.  And that may be true, but I believe that you at least need to give them 20 hours before deciding if they're going in the right direction for you.
 
Some people think burn in is a myth, but with respect to tubes, it's definitely real!

Ok, thanks. I'll put them back tomorrow

I was thinking... anybody has list of Lyr compatible tube types ?
 
Found some on "local ebay" :

Anybody knows which ones are usable in Lyr ? If any of these are I could try them

 

[Joong]

6n1p, ecc88, the numbers in the first line indicates compatible each other and Lyr.
The rest of them I don't know, possibly not compatible with Lyr.

Are you these any good?  http://www.ebay.com/itm/Matched-Pair-Reflector-NOS-Military-6N23P-EV-E88CC-6922-6dj8-ECC88-Tubes-/170997877193?pt=Vintage_Electronics_R2&hash=item27d04489c9

 
That is a really awful price, wow the nerve on some people (vendor, not you).  For $50 you can get a pair of Amperex A frame dimple getters.  Don't mess around with that garbage unless you are desperate.

I bought a pair of NOS Telefunken E88CC 6922 Siemens 60s without <> mark.
The seller said that "No <> on bottom, because tubes are Siemens tubes from the 60s"
Anyone can comment about this ?

 

[toschek]

It's possible I guess, I would look for the diamond if I were spending Telefunken money though.  It sounds like you already pulled the trigger though?

 

[Joong]

I did...

But the seller rating is high and German

.
I need to test when they arrive.
 
If they sound noticeably different than GE stock ones, otherwise they will be returned.
I bought them 160 USD.

 

[toschek]

$160 isn't too hard to swallow. The German mfgs did occasionally buy tubes from each other and badge as their own (Siemens/Telefunken/Valvo) so you might have gotten one of those. If you did then all's well.

I'm just leery about this because there is a lot of fakery with these high value tubes.

Edit: do they have gold pins at least?

If the Telefunkens don't have diamonds on the bottom, then they were made by Siemens.
