Hello you guys, especially Gray Rollins.
Working on a balanced Tubed Phono stage too.
Lundahl 9206 Transformer, Diff. Cascode with floating RIAA between the anodes, current sourced
(transistor) and another Diff. Amp as 2. Amp/Driver.
has anyone better suggestion? As I saw Gray Rollins is working on a balanced Phono. Can you provide some Info.

That's a good way to do it. The cascode does a great job reducing input capacitance. You can also replace the input tubes with jfets for more gain.
I'd almost suggest splitting the RIAA between gain sections and adding a follower-type buffer for the output. But if I did, you'd build what I have.

Check out www.vacuumstate.com and look in schematics at the RTP series. Amazing linearity and SNR.
