Another thought. I can do a -100V negative regulated PS. 100V on CCS. 350V on 6SN7 for inverter stage. 200V on 6J5 for gain stage. It has no issue to output 10V peak to peak to drive 6SN7.

A cascode MOSFET CCS using 8N100D2s only requires 30V across it. With 100V a resistor could work (not as well); but you would have to calculate the difference in plate loads to achieve equal amplitude outputs. With a very high impedance CCS plate load resistors are matched.

  CCS + resistor = problem solved.
