Schiit Lyr Tube Rollers

A few different angles with a bit more light please so that the internal construction can be seen.

 
 
http://imgur.com/a/0fBRs  Here's an album.  I'm not sure if that strange residue is just gunk, or it was an actual symbol of some sort.  It's on both tubes though.  But it's so worn you can't tell what it is.
 
Hopefully this is a little bit better, my tablet takes horrible pictures unless I mess with it for like 5mins per picture.
I'll try taking some with my camera, hopefully I can get better ones for ya.
 
Lemme know if these help.
 
Edit: camera ones turned out worse, the flash overpowers and shines off the glass, turning the ISO way down doesn't help, and turning the flash off and the ISO up just makes the picture almost black.
Man I need a new camera :frowning2:

Is the getter the little metal circle at the top of the tube? I'm not entirely familiar with all the slang and stuff.  (things like pinched waist, getter, etc I have no idea what they are)
 
I'm quite new to this!

This is helpful in terms of understanding some of the lingo.  The Lyr takes the 6922/6n23p/E88CC etc.. family of tubes.  These are dual triode signal tubes , 9 pins, 6 volts.

Triodes as they evolved over 40 years of tube manufacture, from the RE16 in 1918 to a 1960s era miniature tube.

  Has anyone compared Lyr2 vs Lyr1,  my Lyr 1 died and I want another with that great tube/mosfet sound.  If this has already been discussed please point me to the thread number.
 
thank

Check MarkSF's posts he has had both the Ly1 and Lyr2 and I believe he's posted some comments on the two.  The Lyr2 is slightly quieter due to improved power supply filtering and DC heaters.  It also has a gain switch for very low impedance phones like the AKG 701/702s and IEMs.  Due to the change in circuit design the Lyr2 can not use the 6n1p/6n5p and equiv tubes.  Otherwise the two amps sound very similar from what I've read.
 
What will likely make for a bigger difference in sound are the quality of the tubes plugged in - what the 3,743 post and 131,764 views of this thread are all about.

Happy rolling!

Edit - PS If your looking to save money - lot's of really nice Lyr1's on the market - very cheap.  Mine is dead quite with the HD800s. So it all depends on if you have low impedance cans or IEMs then the Lyr 2 is a must.

I purchased the Lyr from Amazon (new) about 3 monthsago, and I use it with low impedance HP's and found with higher quality tubes the Lyr has no noise floor…otherwise you can hear the noise floor. 
Some tubes can go noisy, which can be two, actually three types. A steady low level hissing, a sporadic crackling or a ringing sound called microphonics. This is generally an infrequent problem for well screened tubes. My Voskhods are very quiet - deep black background. But I'm using HD800's.

I'll add a fourth, which I mentioned earlier and linked to a Wikipedia article that explains it.  A 60 Hz ground loop hum.  Mine has decreased in intensity as I've burned in the tubes, but with no music playing it's still audible.

I've encountered all of the above with noisy tubes in the Lyr using Grados, but when I used the HE400i the noise wasn't as audible, if any. Right now I'm using some '60's Telefunken "0" Getter Gray Plate  ECC88 6DJ8/6922 tube in the Lyr and the noise also is as audible if any with the Grados.

I've also noticed the decrease in noise after burn-in.

  I have a son who swears his apple earbuds and iphone are all the audio he'll ever need.  And has never bought a single cd, track, or download.  It's Spotify streaming all the way, everyday.
 
Hey whatever works for you guys is great!  Happy listening!
