Second Gain Stage Cathode Follower & CCS for 6AH4 + 6BX7 tubes - Bandwidth Audio Project 2845 Part 4
In part 4, we investigate and proposes ideas for a second gain stage and driver that can meet the demanding requirements of a SET amplifier using parallel 845s. Large signal swing and high output current in the preamp are needed to achieve full power. We also discuss the merits for using a constant current source/sink CCS in this amplifier.

If you lower the value of the grid stopper you may extend the frequency where you see that very large Z for your CCS.
This is a little over my head, but I'm here to learn.
Thanks for explaine. Tony italy
