It is not a gyrator. It is just a source follower for the filtered voltage. No harm done. Gyrator would have a positive feedback through capacitor.

Why do you use a gyrator in PSU? Gyrator would actually cause power to sag on sudden current draw on sudden peaks of AB2. Two things spring to mind. 1) Yes, ...

Decided to test using an electronic Gyrator in place of the PSU choke. This was a case, where Spice really did the trick, as the simplicity of the schematic belittles ...

... in front end instead of 6N1P as already had this tube available. 2. Resistive loading instead of gyrator of the first stage (20kohm for 12AT7). (have not managed to make the gyrator PCB yet as I ...

... 6J5P in triode plus 6N16B as a cathode follower to drive 4P1L. 6J5P will be loaded on BSP225 gyrator.

... Amplifier works great. Very powerful and good sound. Thank you so much. Will slowly make the gyrator and put into the circuit when I have a bit more time. Congratulations! ;) Consider it as a ...

... as driver stage for both channels. Currently using resistive plate load for 12AT7 instead of gyrator due to time constraints (will do it once have some time available). Coupling caps are FT3 ...

I meant triode 6P14P but using a resistive loading for the 6P14P instead of gyrator? No, Rp in triode is too low for my taste... But if you like sound of RH 84 you may try. Triode stage ...
