And one last thing, could you re-explain how you advise to shield the
FET ? I don't see what you mean :-(

Thanks for your answer ;-)

let me explain this a little more visually.

to begin with, i imagine that you are building this ugly style over a
copper clad board. Now, imagine that you have soldered another piece
of copper clad board (about an inch high and 2 inches across) so that
stands vertically at ninety degrees from the base board.
Now imagine that you have cut out a small mouse hole in this 'wall'.
The size of the mouse hole is just enough to let the FET's body (and
not the leads) pass through.
You take an FET, bend its drain and source to ninety degrees and away
from the FET body. Now you slide the FET into the mouse hole. Bend
down the gate and solder it to the base copper clad board.The source
and drain leads should be on either sides of this wall (the sheild).
this will prevent the source and drain from coupling the energy back
to each other.
