Jim,
For that inductor the amps I have that perform well use it. All three use different
arrangements and all produce 10W and do it well.? One its a Ft50-43 with 8turns,
the other its 4 turns on FB43-202 and the third uses a stacked pair of
FB50-43 and 6turns bifilar #26.? ?
In all cases the output translation is 2:3 turns or more for a low drain load and the
feed inductor does not need to have an especially high inductance.? They are?
in the range of 4x the load impedance at the lowest frequency (3mhz).
One of the things to avoid is self resonance as well.
