power SSTC plans?

Hi,

are there any plans on the web on building higher power (>100W) solid
state coils? 

I've seen many schematics for the simple TV flyback coils, but what I'm
searching for is some powerful RF frequency generator with low voltage to
bottom feed a small, maybe 2"-3" dia coil.

Would a switch mode PSU with adjustable freq and no output
filtering/smoothing do the job? Is there any difference if the PSU output
would be high(er) or low voltage?

And, how does base feed work - do you hook up the secondary coil base
directly to the rf generator, a bit like an antenna? Or connect a helical
primary below the secondary base and connect the generator to it, so
there's alternating magnetic field through the secondary plus a RF signal
at secondary base?

many thanks,

Jan
