Plate supply after Pi filter/choke?

[LeftyStrat]

Anyone tried a Gyrator (Electronic Choke)? They are starting to appear quite regularly in supplies for DIY HiFI Tube Amps.

EDIT: For those who are wondering what I mean I have added the following example.
With the link at the bottom out, it works like an electronic choke. That is it opposes current change and presents a high impedance to residual ripple. The series resistor after the choke will develop a current dependent voltage across it, and that is fedback, via the cap to the MOSFET gate. OR you can think about it as an inverting amplifier with a capacitor in the feedback, making it behave like an inductor.

With the link in, the electronic choke action is reduced (by capacitor divider action) but capacitance multiplier function is added.

Thanks for sharing that. It would be interesting to experiment with this.
