TUBES: Telefunken EL84 & ECC801


Hello. Who's familiar with sound of vintage 60s military Telefunken E84L (el84) and ECC801S (ecc81) ?

Can you guys recommend me something better than telefunken? I have a set of these Telefunken tubes in my WLM Minueta class-a push-pull and i like it, but this is the only one set of hi-end tubes of highest quality i have. Need to secure myself and buy another as a spare set. Also i'd love to try something better if possible. I listen my WLM in triod mode with Druid MK5 speakers of 101db and love it. I must say when i changed stock tubes (modern JJ & Tungsram) to vintage nos military Telefunked the difference was huge! I believe only with Telefunked i realised what is the tube sound.

I'm considering some other hi-end NOS tubes of that kind from different brands or maybe some top of the line new reissue tubes (i'm still doubt they can compete with Telefunken).

Need help.

Re; Tube sources, just had a terrific experience with Brent Jessee.

Anyone tested affordable Sylvania Gold Brand 6201 vs rare Telefunken ECC801? 
I decided to post my updates here:
Got this set of gold pins Sylvania Gold Brand 12at7WA

... and i must say this is the first tube that i really like compared to my Telefunken ECC801s. What a great experience, this Sylvania sound is something special, i think i have more flow, definitely more bass and while the top end is not so extended as with Telefunkens i still love the highs of Sylvania. very comfortable tube in my system. I think the gold pin version of Sylvania GB is rare, but still not so expensive as Telefunkens.

Now i’d like to replace my power tubes:

Telefunken E84L which i’m uning now with those Sylvania preapm tubes.

So the question is what can be really good as a direct replacement?

What about late 50s, early 60s cylinder "no hole" plate RCA smoke glass 6BQ5 tubes?

Mullard CV4024? Never tried, but they are widely available NOS in every tube shop as i can see (under $50). The Sylvania Gold Brand is not so easy to find, especially gold pins.

Anyway, not i'm looking for power tubes (6bq5/EL84) for back up, those Telefunken E84L is so rare and i want to put them aside for some time. 

I'm happy with Sylvania 12at7/ECC81 as an alternative to my telefunken ecc801s.  Can't buy every tube i wish to try, unfortunately.
