Einstein V1 TAD tube problem !

[kunfi]

Hello,
Since two weeks, my Einstein has started to crack and to buzz strongly.
After many tests, it seems to be the "V1 TAD tube" that doesn't work anymore.
When I put the V2 ruby, on V1 for test, all seems to be OK.

Which tube can I get to replace the TAD on V1 ?
The original TAD is a bit difficult to find.
I would like a tube with more harmonics which match well with the Einstein.

Thanks.

12AX7 Chinese highgrade non microphonic type is best
for distortion. ECC83-JJ delivers a better clean.

I don´t think we have a "PROBLEM"

Someone has experienced a new tube on V1 for the Einstein ?
I really don't know wich one to get...

Well it's really just about preferences. I like the Svetlana/SED 12AX7 in that slot personally.
