I came to the same conclusion after I burned my PA...

I have installed 2x1Ohm in place of L14, 100n+10n from the T1 center tap do ground. Still have around 3.5W out.
Now the hot spot is T1, I wonder if wiggling with windings can improve something. On the other side less loss on the T1 may equal higher load to the BS170 team.
