Is there a recommendation for the torque for Kendo / Ekstatik on Ekos SE with Klimax LP12?

I believe it's 0,4 Nm + 2 notches. The tracking force is 2,1 g and the anti-skating 2,05 (Ekstatik).

Yes, .4+2 notches is what I found for the Ekstatik. I expect the Kendo to be the same. Originally I found tracking force best at 2.1 grams but I have found they vary a bit from one to the next with some musically the best at 2.0 others a little higher up to 2.1. Best to try around that area until you find the most musical setting.
