Just purchased this from The Tube Depot:
 

Philips Miniwatt SQ E88CC / 6922 Gold Pin, Holland

We unearthed a stash of Philips Miniwatt SQ E88CC / 6922 Gold Pin tubes made in Holland in 1969....
 
Can't wait to hear them!  I researched all day, and these seemed like one of the good buys.

Guys is it normal that the 6BZ7 in my Lyr-2 sound a bit muddy (mostly on low volume) on the start? 
They have only about 10 hours of playing now. This is part of the burn-in? 
How many hours do they need to open-up? 50 hours? 100?

  I would let it burn in a minimum of 100 hrs.

Always good give at least 50 to 100 hours burn in to let the tubes smooth out...

Give them the other 40 hours or so then reevaluate.  If it still sounds "muddy" then begin to look in other directions.  I was never a fan of the stock tubes from Schiit.  You may wish to check out other tubes.  Of course YMMV, IMHO ect...

Yes, I give it some time like a good wine :wink:. I give it about 100 hours playing and see what happens. Hopefully they open up more.
Which pair of tubes you prefer/recommend for about 100 euro's?

  70' era Siemens CCa A-Frame Construction. One of the best sounding pairs of vacuum tubes IMHO. I have a pair. Price can range from $235- $390 depending on label condition, and w/wo box.
 

Thanks alot for the reply and the information! been searching on the web all day for information but din't really find all too much
except a picture of a siemens cca that looked like it from tubeworld (left one)

  Hey guys
 
do u guys know wich Siemens this one is ?
how much would it be worth?

As spyder1 said, A-Frame getter supports from '70s. Should be a metal tag inside the tube attached to one side of the A-Frame just above top mica, it will you give you the production codes.
Paint can vary but the code tag will give you the factory and date.
 
Upscale Audio sells these for $180 each.   http://www.upscaleaudio.com/6922-6dj8-7308-pcc88/siemens-cca/
