LL1660 as Autotransformer

Hi to all,
I had LL1660 on hand and like to used it as headphone amp OPT.
The circuit use either 5842 or 6c45 loaded with CCS then parafeed to
ll1660 which to be connected as autotransformer configuration 8.5:1 (all winding in series and no dc current).
As my heaphone imp. is 62Ohm, the reflected impedance seem to be acceptable for both tube. The maximum expected power output to HP is 200mW.

Now I just wonder whether ll1660 will work in this configuration?
How shoud I connect each winding to maximize freq. response?
Or any other points you guys can come up with.
