OK so now I modeled the plate capacitor.
When 100uF plate capacitor is used with the 100uF ultrapath and 100uF cap below it, (as per BB Proof Rev 1.2 drawing), the wiggle on the cathode of the 2A3 is 2.62V
Without the 100uF plate capacitor the wiggle is 2.75V (As mentioned in the previous simulation.)
Unless someone can point out additional attributes that justify the use of the 100uF plate capacitor on the 6J5, I would say it is not worth it.
The 100uF is better combined into the other positions. (Ultrapath and lower series capacitor.)
I ponder the idea of paralleling 100uF caps for lower ESR to offset the series ESR, or to just get some bigger electrolytics.
