In Reply to: Cathode Follower Line Stage posted by Triode_Kingdom on May 15, 2017 at 19:10:47:
I built one in this general flavor. Instead of a choke I have a bi-filar output in the cathode. Also, instead of the triode, with its poor current PSRR, I stuck a MOSFET on top in cascode to improve this and deliver minimum input capacitance. I am running a 5687 at 20 mA.
Where do those chokes you have go self resonant?

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
