Ayre V3 proto topology for preamp?

[maxpou]

Hi Guys or Mr. Hansen,
is it possible to built a line preamp with the topology of Ayre V3 proto if i replace all mosfet with Jfets? Thank You! Maxpou

Hi guys,
this is the schematic, i don't need balanced input. Does it can work? Thank you! Maxpou

Hi Guys,
i test the circuit but i have a problem with my dc offset. I adjust with my R8 and R9 for 0Vdc at the output without signal but i input signal my dc drift at output. Why? thank you! Maxpou

My schematic with value of components. Thank you! Maxpou

In principle, you can use the amp's topology to create a preamp, but I don't see that you're following the V3 topology--at least as I remember it. If I have time, I'll dredge up the schematic and see if I'm right.
You're putting a signal in the Source of Q3 & Q4 and taking it off the Gate? There are several oddities about your schematic.
