Hello,
I used LL1674 as a parafeed output of my Audio Note DAC 2.1x in 4:1 config.
I tried it with Jensen tin foil 1uF cap and Audio Note PIO copper foil 0.47uF. Jensen was a nightmare, poor transparency, poor HF and bass, but 0.47uF AN sounds great with deep bass, very good MF, HF, timing...just fantastic. So even 0.47uF can be good if a cap is good. I didn't have any other coupling caps, so maybe big plastic like Kimber or Aricap 2uF would do the job also.
I hear better notes separation and transparency, but not lean at the same time. I'm a bit supriseed it works in a AN circuit...Maciej

to the plate of the bottom tube instead of the cathode of the upper one?

No,
I think that it is a nature of SRPP to get the voltage from the upper tube cathode. Maybe I should try it...
If it was Mu stage yes, it shoul be connected to the lower tube anode. Can someone more skilled comment it?

the cathode of the upper tube as well. Just like the SRPP...
But I was simply curious..if you have tried and listened to it otherwise...
