Hi Jim,

Very cool!  The control hookups are trivial.  The current is lightly 
low for a SISG but a little loading resistor on the feedback CT would 
probably fix that ;-)

Inverters can be bought new for about $80 or salvaged free if you can 
find a working oven with one that is being thrown out.

The real question is how would the control react to a firery Tesla 
coil load??  The current would jump wildly!!  The little chip 
"should" see that as an acing tube or something and shutdown.  But 
there is not a lot of feedback there so the circuit might be easy to trick >:))

Cheers,

        Terry
