Leave things as they are! The Miller capacitance of a 6SL7 section is substantial. The very last thing you want to do is introduce HF rolloff.
RP in a 12B4 is approx. 1100 Ω. As 9 KOhms is considerably more than 3X RP, you can relax. :>))
BTW, the "corner" freq. for 3.3 μF. working into 9 KOhms is 5.36 Hz. While not terrific, that number is certainly tolerable. A F3 <= 5 Hz. is the goal.
