As a rule of thumb R380 and a min C100
It really does make a difference to get it right
I’ve just got my Mastergroove back from being upgraded to SR and when I played it initially with R500 there was no low bass and little dynamics
Setting it to R100 which is correct for my cartridge, this changed it completely and the sound was back to where it should be albeit much improved due to the SR upgrade

Try to contact Peter from @Cymbiosis, a really friendly person. He gave me the right resistor and capacitor for my Linn Kandid as an airplug late last year and I’m still excited about this setup. Maybe he also has the right values for the Benz.
