Here is my guess - and that's all it is.
In simulation the start up current is very high so i suspect your inductors were saturating ceating an "almost" short. The 2 inductors seem to have solved that problem. So now the bigger the part the higher the current. Since it is F2 you might get away with a slightly bigger fuse but you are probably getting close to what it can do. What frequency is it running at now? I think you meant 10 X 220nf, not Ufd.?
