Guido,

>>> It sounds strange, because to have 45,6 uH with 20 turns the Al should be
1140.

Thanks a lot. Sure I was wrong with inductance.
For 20 turns:
T-300A-2 AL=228, L=9.12uH
T-300-2   AL=114, L=4.56uH

To get same inductance on T-300-2 need to have 28T. But coupling will
between primary and secondary will be changed. How much it critical ?

Regards,
