Well my SSTC-s newer seem to work ( Steve Wards design) and i was not able 
to get anymore gate drive cjips. So i tried Richie Burnetts first supressed 
design with halfbridge of IRF740 and TL494. It works perfectly, makes 8 cm 
sparks at halfrectified 220 V and 30 primary turns. The great thing is i 
never had somuch sucess from run ning a SSTC directly from a line. My 
previous SSTC blew allready at 50 V.

Now i have a question

How to percectly tune it?


Here you can see pictures of it ( Terry will attach them):

It is currently dissasembled because im going to put bigger fets inside ( 
irfp460), but even the poor IRF740 did never heat. And check how "BIG" it 
is, you see a simple small lighter?
