Here is a partial list of tubes that I use in my LP (w/o issue for me)

12AU7 variants

1. Mullard Blackburn ECC82 long plate square getter UK B- factory code
2. Mullard Blackburn goal post getter ECC82
3. Brimar CV491/12AU7/ECC82 Long Plate Square Getter England 1958
4. Valvo 12AU7 ECC82 Germany, Hamburg Made Tubes (GfO D9E), SlantedGetters
5. Telefunken ECC82 Smooth Plates
6. Siemens ECC82 Silver Chrome Plates 12AU7 [LP]
7. Amperex Holland long plate foil D getter 7316 / 12au7 1958 (Beckman label)
8. Amperex Holland long plate foil D getter 7316 / 12au7 (2 singles)
9. Amperex PQ 7316 ECC186 12AU7 D Getter matching 461 codes
10. Brimar ECC82 1970s HALO-DISC Getter Short Plate Mazda LABEL - Thorn-AEI - England
11. Tesla (NOT JJ) 1975-82 Military Long PL. ECC802S prem. 12AU7
12. RCA 12AU7 Black Plate Square getter 1957
13. RCA 12AU7A Clear Tops Conn label
14. CBS Hytron JHY 5814A/12au7 Black Plate, Bent rectangular Getter a8
15. Sylvania JHS 5814WA/12AU7 Military Triple Mica Black plates code 5639B 312J
16. Baldwin Raytheon 12AU7 long shiny black plates (6 pairs)
17. Marconi MWT B329 ECC82 BRITISH MADE

All of the above are 12AU7 / variants that the Tubemonger adapters will work with in you LP

It depends on what type of sound signature you like but the Mullard Blackburn ECC82 long plate square getter UK B- factory code are phenomenal tubes however can be expensive. To help find the sound signature you like I would recommend trying:

1. Brimar ECC82 1970s HALO-DISC Getter Short Plate Mazda LABEL - Thorn-AEI - England
From Tubemonger as the are really good tubes for a reasonable price at $80 for a pair ($40 each tube)
https://www.tubemonger.com/MINT_NOS_BRIMAR_ECC82_12AU7_1970s_HALO_DISC_GT_p/1236.htm

And for a different sound signature try these

2. Tesla (NOT JJ) 1975-82 Military Long PL. ECC802S prem. 12AU7
https://www.tubemonger.com/Tesla_NOT_JJ_MINT_NOS_1975_82_ECC802S_Tall_PLCZ_p/1012.htm

Both of these tube are really good! As I have both and really like both for different reasons!

Hope this helps!

@jb77 : The list and suggestions are very helpful indeed. Thanks. As for my preferred sound signature : I listen to a lot of Jazz : all types, Classical, modern, avant-garde, even some fusion and blues. I also like some Classical, Acoustic music, some types of world music and other genres (but I'm not so much into techno, EDM, Trance, and genres that are close to those categories)... Accordingly, I like to hear each instrument, and its player, separately, preferably on a wide soundstage, with lots of "air," extension at both ends of the spectrum, and depth --the more 3d-like the better... Things work best if the retrieval of details (both macro and micro-details--or plankton) is great without sounding harsh, analytical, or fatiguing. Of course bass, which extends deep while retaining texture and punch is also welcome...

i do not expect a tube to do all of that by itself... I know my DAC and the LP also have a part to play in defining that desired sound signature, but I think those I have already do quite well. However, I never rule out the possibility that they can do even more with a little help from the right tubes...-- They already work quite well with some of tubes I already have, but I am hoping these 12AXX types will bring something new (and hopefully, even more exciting) to the table. I'm always hunting for better sound, but I am thinking that is what most enthusiasts always want, regardless of what they already have... I see that endless search both as the blessing and the downside of this hobby (although "downside" is probably too strong a word?)

No problem glad to hear they were helpful.

If you can I would actually still recommend both of the tubes from Tubemonger in my previous post as both pair will be $170 plus shipping which is about the price of, or a lot less expensive then other tubes in my list.
The first option I listed:

Brimar ECC82 1970s HALO-DISC Getter Short Plate Mazda LABEL - Thorn-AEI - England $80 for the pair ($40 each)
https://www.tubemonger.com/MINT_NOS_BRIMAR_ECC82_12AU7_1970s_HALO_DISC_GT_p/1236.htm
The Brimar’s are going to give you a little more warmth in their sound

Tesla (NOT JJ) 1975-82 Military Long PL. ECC802S prem. 12AU7 $90 for the pair ($45 each)
https://www.tubemonger.com/Tesla_NOT_JJ_MINT_NOS_1975_82_ECC802S_Tall_PLCZ_p/1012.htm
The Tesla’s are going to give you more top end sparkle w/o being harsh (well for me they are not harsh)

For me both have a relatively good soundstage and imaging.

The most 3D tube I have heard is the
Amperex Holland long plate foil D getter 7316 / 12au7 1958 (Beckman label)
You will find other 7316 tubes, however the ones you would want to look for are specifically the 7316 Amperex long plate D getters, these can be hard to find and can be expensive.

The CBS Hytron JHY 5814A/12au7 Black Plate, Bent rectangular Getter a8
Is the best tube for bass I have and a worthwhile purchase as it is also a “fun sounding” tube

The Telefunken ECC82 Smooth Plates are also a worthwhile purchase.

IMHO I believe any of the above mentioned 12AU7 tubes will give you “better” sound than most any of the 6922/ECC88 tubes with a few exceptions such as the:
1950s LORENZ STUTTGART - PCC88 Grey shield, 2 mica
or
1950s SYLVANIA - D getter 6922

Hope this helps

Damn! You have some nice ECC82's. Bet they would sound killer in my BHC!

Thank you!
I have done a lot of tube hunting in a relatively short time. For my MJ2 I have also branched out into the 12AT7 and 396A/6N3P/2C51 Tubes, this really is a fun hobby but man you really can spend some $$$.

For your LP have you tried:
1950s SYLVANIA - D getter 6922? these really are great 6922 tubes!
Not sure if you would try these as they are PCC88 however:
1950s LORENZ STUTTGART - PCC88 Grey shield, 2 mica, are phenomenal tubes in the LP

Also this is off topic but how do you like your ZMF Aeolus?

 

[mat.1]

Anyone can recommend me which 6922 tube from upscale audio that work best with liquid Platinum around usd 200-300 budget for match pair ?

Amperex 7308, if only going with Upscale Audio.

Amperex 7308, if only going with Upscale Audio.

is this the one https://www.upscaleaudio.com/products/amperex-7308-vintage-gold-pin ?
Is the same as 6922 so there is no adapter needed ?

thanks.

Yes. That is it, and no adapter needed. 7308, is military version of 6922, with tighter tolerances, and therefore better sound.

I'm going to want that Stuttgart pair back as I only have 2 pairs.
Valvo PCC88 Hamburg PW 57 is a glorious tube also. Running that in my LP.

I got these ebay adapters https://www.ebay.com/itm/232415799770 but they dot not fit the liquid platinum - diameter of the adapter two large for the holes of LP.What 12AU7 adapters are you guys using?

I highly recommend purchasing these you’ll need two of them https://www.tubemonger.com/NOVIB_Socket_Saver_1960s_NOS_British_McMurdo_B9A_p/novib-mcmurdo.htm

They are socket savers not adapters, however you would want to use these then put the adapters in these, because if you just put adapters into the LP, when you would want to try and remove the adapters it would be extremely difficult, unless you have socket savers. The Tubemonger brand has the best socket savers I have ever used also with their vibration resistant basses on the socket savers it will help any microphonic tubes you might have.

Tubemonger also makes adapters, that have the same build quality of their socket savers. They are currently out of stock of the adapters, though they will have more in very soon!
https://www.tubemonger.com/12Axx_to...IB_1960s_p/12axx-ecc88-adap-novib-mcmurdo.htm

Hope this helps, also I posted a couple of pictures of my LP with just the socket savers in (so you would be able to see what it looks like) and with the adapters plugged into the socket savers, so you can see what that looks like as well.

Thanks. This is very helpful. Can you remove the socket savers if you need to?

 

[TK16]

Thanks. This is very helpful. Can you remove the socket savers if you need to?

People have had an awfully hard time removing them.

 

[jb77]

Thanks. This is very helpful. Can you remove the socket savers if you need to?

As TK mentioned it would be very difficult to remove them, however for myself I have no plans on removing mine as they make tube rolling much easier, being they are socket savers they simply pass through the signal from the LP. so if you were to use 6922 variants you would simply insert the tubes into the socket savers.

Hope this helps, also here is a picture (below) of the LP with 6922 variants as they simply insert into the socket savers.
