Default Raven using Lundahl instead Sowter

I would like to build a PP line stage preamp..something like the Lynn Olson's Raven..but using Lundahl irons..

Anyone have some scheme to suggest me..? To send me?

It's not important the tube..not only 5687 like in the Raven..6sn7..6j5..e182cc..are welcome too..

I've not a big experience about..

Really thanks if anyone can send me some scheme..line +PSU..

Regards and greetings from Italy.

The LL1674 is excellent for this application (both as input phase splitter and output (amorphous cores ). I bought a Raleigh Audio PP kit from K&K audio that uses the LL1674.

Sounds sublime.
