Jadis with Telefunken 12AX7/ECC83 tubes

Hello,
After hearing few recommendations of Jadis users I have tried Telefunken NOS 12AX7/ECC83 tubes in my Jadis equipment. I put three tubes in lins stage of JP80MC preamplifier and two tubes in JA80 monoblocks.
I have mixed impressions. These tubes gave very good top end extension and sparkle. The sound was more transparent and some new details appeared. Also the soundstage improved in 3D depth. But some magic of midrange has gone. The Telefunken tubes pushed this a little romantic tube sounding set more into very good solid state set. I am not sure if the overall effect is what I require. Jadis is for to die for midrange and installing the tubes like Telefunkens pushes this set into a little different presentation. I am not sure if I end with these tubes and I am curious other Jadis user experiences with signal tubes rolling.

Well, I still prefer the Teles (I think they are the best overall performers through the entire frequency range), but my ears are different than yours. I agree with Rodman that Amperex Bugle Boy tubes would probably add some of the warmth you crave. I used them for the 6DJ8s in the phono stage of my preamp, liked them best of all tubes in that position, but unfortunately they eventually would become noisy in less than a year. My experiences with Mullards in my JP80 (not the JA80s, where I liked them) was not so good, but I have the feeling I might not have had the real thing, based on others' comments about them.

My experience mirrors that what Rodman and Rcprince have to say. In my Jadis days I stuck to the Teles and spent a fortune on finding the right Amperexes for my phono section. Cannot recall exactly if I finally settled for pinched waists until they also turned noisy.

In my older Defy7 I prefer NOS Tungsol 5751 with ecc82 TFK driver. The second possibility could be TFK ecc83 with NOS RCA black plate 12au7. When all seting composed from total TFKs the sound lacks timbre, basis and air.

>Milimetr try 5751 in JA80 monoblocks?

- how do you identify first tube in the JP80 preamplifier line stage - counting left to right? I thought that left and right tubes should be the same and the center tube may differ like (it is positioned with pins toward other side).

- What Tundgols do you suggest - can it be gold pins from current production? I heard good opinions about them.

- I have 5751 JAN GE - I used them before in DA88S.

- Waht input tubes do you recommend for inputs in JA80.

I forgotten to mention that the set is 25th Anniversary Gold special edition - a little different than standard edition, but it does not matter in tube rolling.

So far I returned in preamp to stock Electro Harmonix and overall prefer them than Teles in preamp.
