Schiit Lyr Tube Rollers

Lyr owners looking to share their experiences with different tubes or learn where to go after the GE/JJ stock tubes can come here to consider the personal opinions of others.

To get the knowledge base rolling, here are some resources that I have personally found worthwhile.  Others can chime in and I will update this post.

Where Do I Start?
Previous Lyr Tube Rolling Thread:

Joe's Tube Lore:

What is the consensus?
There is no consensus to rely upon really.  Everyone has their own preference in terms of soundstage, brightness, etc.  Further complicating the issue, different tubes may sound better with certain headphones.

Then what good is this thread?
If you have an idea of what you are looking for in sound reproduction, the reviews posted here can guide you toward certain tubes that are most likely to compliment your system at different budgets. 

What are some of the more popular sub-$100 (per pair) tubes to consider?
'60s Amperex 6DJ8 "Orange Globes"
'70s Voskhod 6n23p "Rockets"
National Matsush!ta 6922/E88CC

Compatible Tubes
6DJ8, 6922, ECC88, E88CC, 6BZ7, CV2492, CV2493, 6N1P, 6N23P

This link will take you right to the above mentioned section:

I expect this is a negative, but does anyone know of any ECC89 to ECC88 adapters that are available at retail?  During the initial Voskhod hype, I jumped on an auction for 3 6n24p Rockets (2 '71s and 1 '73) not realizing that it wasn't a 6n23p auction.  I don't think I'm crafty enough to make my own.  They were incredibly cheap at least.
  I have a pair of '79 silver shield rockets burning in at the moment.
On another note, does anyone have a comprehensive list of compatible tubes?  I'll add what I can to the opening post but my list will be far from exhaustive.

Favorite tubes for my Lyr / Bifrost Über stack with following headphones:

HE-500 - Lorenz Stuttgart PCC88 3-Mica
T1 - Amperex PQ 6922 Pinched Waist

Yes, these tubes are rare but worth the wait.

Glad to see this up and running. I will be receiving a pair of '65 E188CC La Radiotechnique RTC tubes soon. Can't wait!

I hope you love your La Radiotechnique RTC's as much as I do mine.  Beautiful tubes.  To me delicately detailed across the entire
spectrum and just plain musical.  Enjoy !!
