The CCS isn't a miracle- it just means that the load being driven dominates the cathode impedance. So once the CF is actually asked to drive anything, the CCS is pretty much out of the picture except as a means of biasing.
edit: BTW, there was an equivalent circuit of a plate driven tube posted a couple days ago. This is perfect for calculating PSR.

no of course not, but Aikido does.
Hello StoneT,
for the supply rail voltage ripples the follower acts as a
triode in the transformer mode. link
Kind regards,

Hello regal,Originally #1 posted by regal
Does the PSRR of a Cathode Follower get better using a CCS sink on the cathode?
no of course not, but Aikido does.

Wierd, I just posted pretty much the same question but more like 'why doesn't it get better?'

Now I am going out there but would PSSR be better with a
CCS GC -> CF CCS Sink vs. a SRPP?
Just trying to decide if I should revamp my SRPP DAC stage, I hate the fact that its lowest distortion is into a 6K load. Getting glare in the upper mids. No room for an Aikido or new PS.
