	To the person questioning what kind of amplifiers would 
be necessary to drive the primary of a tesla coil:

	50Khz to 500Khz? Easy. Power transistors can easily 
handle that. Bias a couple of darlingtons in totem pole, and 
drive them with an op-amp. Mount the power components on bulk 
metal to sink the heat. It is well within their frequency 
response.
