The datasheet for the LL1689 is not yet finished, but I can tell you that the PP version has 290H of primary inductance used as I wrote in the last post and has the same core as the LL1660 and LL1671. The LL1671/PP can be used but has only 80H primary inductance connected as 2+2:1. You would need a lower driving impedance (~4K or less, plate to plate) than with the LL1660 or LL1689.
