Hi,
My K2 SN 4307 is under construction.I finished first part succesfully,without any problems.Ad now I'm in part two, at point with winding toroids.I did it exacly following manual - I mean RFChokes RFC14, RFC16, RFC11 - number of turns and dark grey ferrite cores,diamater 9.5mm -all are correct. Because I have LC bridge, I checked inductivity and I have been suprised.Inductivity of RFC14, 16, 11 are 4x bigger than is written in component list [Appendix A].For example RFC 14 have 60uH instead 18 uH. My LC bridge is OK, I checked it. I suppose is something wrong with my toroid cores, Maybe I have got another kind of magnetic material or mistake is in component list.Could somebody advise me what is more important, number of turns from manual or inductivity.[In my opinion inductivity]. I can wind my toroids once more [I have a lot of emanel wire 0.35mm] under control LC device. And what about toroid transformers - I could't find infomation about its inductivity.

P.S
Also I have measured another coils and inductors. L33 prewound inductor and T1050 ,T1005 inductors are correct
