Hi Dave,

Wow cool!  I use an RF supply for the same thing but it is heavy, complex, 
and unreliable.  A nice small circuit capable for pumping serious power 
would be great.

I assume it has some type of power or current limiting to protect the thing 
from blowing up.  My RF supply has full output protection so it has lasted 
a long time so far.

Cheers,

         Terry
