I got an answer from Klyne Audio.
SK-2 Moving Coil Preamplifier Switch Schedule
Input Impedance (Switches 0-4)
(Impedance / Closed)
1000 / None, 200 / 0, 120 /1, 80 / 0 & 1, 65 / 2, 50 / 0 & 2
40 / 0, 1 & 2, 30 / 3, 25 / 1 & 3, 20 / 2 & 3, 15 / 0, 1, 2 & 3, 10 4
High Frequency Contour (Switches 5-9)
Contour Switches / Frequency Closed
60 KHz / 7, 40 / 6 & 7, 25 / 5 & 8, 20 / 5 & 9, 18 / 6 & 9, 16 / 5, 7 & 9
15 / 6,7 & 9, 14 / 5, 6, 7 & 9, 13 / 8 & 9, 12 / 5, 8 & 9, 11 / 5, 7, 8 & 9, 10 / 5, 6, 7, 8 & 9
Also be noted SK-1 and SK-2 are phase inverted.
