I have some ZVN0545A mosfets here for exactly that purpose of replacing cathode followers. You may like to try this starting at 2mA (250V supply, 125k biasing resistor). Did you or Dima try Soviet SSG silver-mica for the first coupler? I am using 0.175uF items for excellent results though I haven't compared to teflon.
The 834P circuit is not designed for low distortion (probably why Guy dislikes it) but for "listener-friendly" natural harmonic decay. I guess that accounts for the magic and I too have a corrector for life, though now with vintage moulded silver mica caps in place of the air vanes. My shipment of tuning caps from Ocean was destroyed by our paranoid customs!!!
