Tune L-C to resonate freq of secondary
Drive L-C with square wave at resonate freq of secondary


To reduce the amount of snub required wind primary and secondary of
the ferrite transformer using this method.

1. cut three pieces of mag wire 15' long or so.
   Use nothing larger than 16 guage.
   For more current double number of wires.
2. attach one end of the three wires to anything fixed.
3. twist wire together using a low speed drill till you have about 1 turn
   per inch.
4. wind twisted wire tightly around a ferite dount or clam shell.

5. one wire for push, one for pull, third for output.


try this for snubbing.
Im this is only a guess. 50% less power into snubber
