I can confirm that you remove FL-1 for the 10 meter TX, I did the mod about
a year ago and the old FL-1 sitting in front of me.
I also got the tuned input board from Bill at Omega as a kit, if I remember.
It is a little tricky to tame down on some bands. I had to move the
windings on the coils closer together on 15 meters if I remember. You will
need a really good Dummy Load and a steady hand:) By the way if you do the
tuned input mod, check everything again with the cover on, as there is some
interaction going on.

Wasn`t the FL-1 a band pass/band reject filter to limit operation below 10
meters? If I remember correctly you have to delete this filter when adding
10 meters to this amp. Jim K7RDX
