Wireless Mains Adapter-Frequency etc.?

Ok, Started with adding small ferrite beads to gates, very little difference, changed for large tubular ferrite cores, definite improvement.added 100 then changed to 220 Ohm resistors in gate circuit, ringing eliminated but there are transitions still. Added ferrite beads to the drain leads, instant increase in current and hot beads!! added toroid to the supply, (3 turns on small toroid), current dropped from 2A to 0.4A, much more efficient, adding load - current increased to 1.4A with 6W DC into 50 Ohm, Fets very cool. In this connection there was an additional 0.33uF cap after the toroid. adding 1000uF after the toroid returned the current to 2A as before. This little toroid with the 3 turns has a major effect.
I have not tried inserting Rs in the source ccts yet.
These are the waveforms. There is a difference in the Gate waveforms?
