Default Looking for 12AT7/ECC81 phonostage schematic

I have been searching the net for a 12AT1/ECC81 phonostage schematic.

What I have in mind is like the RJM phonostage, but instead of 6dj8, it will use 12AT7/ECC81. Here is a link to RJM Phonostage.

Has anybody done a similar circuit using 12AT7/ECC81?

Any opinions if this project is worth pursuing? Thanks.

I built this ECC81/12at7 circuit:

Sounds quite excellent, I think I like it better than my 6dj8/6n1p RJM phonostage. Unfortunately, I cannot compare side by side, am using the 6dj8 phonostage chassis and PSU for the 12at7 circuit.

Will listen and see if I can tweak it some more.
