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
