Hi,
could someone explain me how to determine/calculate the input Z of the circuit in the following datasheet please:
http://www.jensen-transformers.com/datashts/10k611m.pdf
In next schematic it is said the 12au7 SRPP could be direct coupled to the white cathode follower of 10k611m datasheet but i don't understand choosen RK values of 1,2k in srpp.

I tried to work backward using formulae given by M.Blencowe,
Rload= Rk(µ-1,5)-Ra/2
but it doesn't compute.
I'm surely missing something but don't see what.
Thanks.
