I got the idea from this threat: https://www.diyaudio.com/community/threads/the-hybrid-sit-parafeed.245321/
But I used them at HV parafeed, around 50mA and 120Vds with the 600ohm tap. A hammond filter choke worked great as an inductive load, foax css, and it also helps with PSU PSSR. The various output taps make a monster headphone amp and linestage and speaker amp at the same time. Damn I need to share my build.
2SK82 has about 75 ohm RP and a 47uF cap is around the ideal value as a parafeed cap.
