Crystal controlled Tesla Coils?

Greetings to all

Last year I started on the building of Tesla coils and became aware 
of the amounts of TVI interference they cause.  To solve this I 
figured that a crystal controlled device would have less harmonics 
and thus cleaner signal.  Right know the rig sits in my shop back at 
home for I am at college, however over break I plan to finish it up.  
Does anyone have any experience with this approach?

For backround on it the crystal operates on 200kc which is feed into 
an 807 which in turn feeds a pair of 813's which  dirve the might 
tesla coil.

I have the schematic in autocad formate for those that are

he made a woman out of the dirt and married her. But when he kissed her,
she disintegrated.  Later, at the funeral, when the preacher said, "Dust
to dust," some people laughed, and the cowboy shot them.  at his hanging,
he told the others, "I'll be waiting for you in heaven-- with a gun."
