I am referring to the link posted by Salas today
https://www.diyaudio.com/community/threads/mpp.154210/post-2818966
as a reference of gyrator use in Paradise supply.
I found an example of a single transistor gyrator here :
Source : https://www.epanorama.net/documents/telecom/gyrator.html
Looking at the FdW schematics, Q5 and Q2 may in fact be intended to work as gyrators,
but is it still true if the Zeners, additional cap and LT1086 current sources are included
in an additional loop ?
The original cap, C1 in the figure above, is now grounded (C19, 22), not sure this makes
a difference. This however is not true for both versions of the Paradise supply.
Somebody more knowledgeable perhaps can tell.

That's the servo's RC input filter. I didn't tweak it. The output series resistors I lowered their value.
Conceptually C20 is C1 xx uF and the CCS configured chip reg is R3 47R "current source"?
