Re: FBSSTC modifications ok?

Hey,

Why was only one MOSFET getting a signal on its gate? They were both hooked 
up to a gate drive
transformer right?

I would just give the 4420 and 4429 the same signal (4420 is non inverting 
right?), I don't think
you need a 4420 just to drive another 4420 and 4429
